Impacts of Clouds on a Solar Panel

Solar panels hold a wealth of benefits, both for individuals and for the world at large. Economically, solar panels guarantee to reduce the expense of electrical power. Environmentally, solar panels can provide us cleaner power, sustainable power that will not need more damage to the environment. Solar power can reach remote areas. It can bring education, or urgently needed medical information.

The results of clouds on a solar panel, though, may reduce those and other appealing advantages.

The impacts of clouds on a solar panel may make it far less efficient in specific parts of the world and at specific seasons.

For that reason, people who are considering solar panels for their homes are typically heard to ask: will clouds impact my solar panels?

Will Clouds Affect My Solar Panels?

Clouds do impact solar panels. The amount of power your solar panels can produce is directly based on the level of light they get.

Completely, bright sunshine, solar panels receive maximum levels of light. During those “peak” sunlight hours, your solar panels will produce power at their optimum capacity.

When clouds cover the sun, light levels are reduced. This does not closed down power production, nevertheless. If there suffices light to cast a shadow, in spite of the clouds, your solar panels must run at about half of their full capacity. Thicker cloud cover will reduce operations even more. Ultimately, with heavy cloud cover, solar panels will produce very little useful power.

The Good News!

The results of clouds on a solar panel can be surprising excellent, nevertheless. Extremely, your solar panels will put out their ultimate quantity of peak power during cloudy weather condition!

As the sun moves into a hole in between the clouds, your solar panels will see something wonderful. They will see full direct sunlight “plus” reflected light from the clouds! They will drink in more energy than they could on a cloudless day!

The impacts of clouds on a solar panel might then produce peaks at or above 50 percent more than its direct-sun output!

Meeting the Challenge

There are methods to satisfy the cloud difficulty.

1. If you often have clouds in the afternoon, but early mornings are clear, intend your solar panels slightly towards the east.

2. Be sure you utilize a big sufficient battery system to maximize the quantity of power kept for usage when the clouds show up.

3. Ensure your controller has a lot of headroom over the ranked panel output power so that it can take in the rises when the sun reflects off the clouds.

Those techniques and more are practiced in cloudy areas of the world where people have run far ahead of the United States in their use of solar panel energy.

Effects of Clouds on a Solar Panel in Germany

Germany is normally a very cloudy country. Read about the climate of Germany, and you will find that it is “temperate and marine; cool, cloudy, wet winter seasons and summer seasons; periodic warm mountain (foehn) wind” according to Nation Master’s website.

In spite of its cloudy climate, however, Germany is by far the world’s most significant user of solar panels. If you resided in Germany, you could offer back to the primary power grid all of the excess electrical energy produced by your solar panels. Why would I even care in such a cloudy climate? If clouds impact my solar panels excessive, I would not fret about offering back to the main grid.

In 2006, Germany opened the largest solar park on the planet. Germany likewise has Europe’s the majority of contemporary solar housing project – a solar village of 50 solar houses that produce more energy than they utilize!

Will clouds impact my solar panels? Even if I lived in Germany, the impact would not be enough to bypass solar energy.

Suggestion: There are few places that are so regularly cloudy that solar power is out of the question. Improvements are being made constantly, as well as solar panels small enough to fold into a brief-case can produce handy quantities of power.

Seven Steps to Install Solar Panels on Your Roof

Solar panel systems have a bright future in the roofing industry and for home and structure owners alike. Solar panels, likewise referred to as solar photovoltaic panels are exceptional tools for decreasing regular monthly electrical costs, supplying tidy power, lowering dependence on standard nonrenewable fuel sources, and including worth to a home or structure. Installing roof solar panels is one of the best methods to increase the worth of a house or building. And, not to mention that federal legislation extended a 30% tax credit for business and domestic solar panel installations.

The following “7 Steps to Installing Solar Panels” can be used to guide both business and domestic customers through the solar panel shopping and installation process, and help make it as smooth and easy as possible.

1. Make your home more energy effective.

Before you begin the solar setup process you first need to analyze the energy performance of your house. Adding solar photovoltaic panels to a home with bad energy performance is not going to provide the outcomes you expected. In some states to be applicable for the tax credit your home has to have an energy audit performed before the solar panel system is set up, making your home’s energy performance vital. Here are some suggestions to make your house more energy efficient:

* Upgrade or change windows

* Well insulate walls and attic

* Replace ineffective warm water heating systems and/or furnaces

* Replace incandescent light bulbs with compact fluorescent bulbs

2. Examine the solar site or roofing system.

Ask yourself a few concerns: Is the roof strong enough to support the panels? Is the offered area big enough to hold the panels? Does the roofing system offer southern direct exposure? And most important, does your roofing system get enough sun light? Solar panels are suggested to get full sun direct exposure in between 9am and 3pm in order for them to be the most effective.

3. Get competitive quotes.

Solar panels are a huge financial investment, however done properly they can provide a considerable return and increase the worth of a building or house. Look around a little and find the best rate. However understand; don’t just try to find the most inexpensive cost. Discover a well recognized merchant and installer with a strong track record. Educate yourself and ask the ideal questions, because often a greater costing solar system might be the much better choice, and in the long run offer a greater return on your financial investment.

4. Research the cost.

Solar photovoltaic panels differ in expense, which is usually figured out by the size measured in Watts, the real measurements, the brand name, the longevity, the service warranty, and any certifications the solar panel may have. As solar systems increase in size so does the price. Anticipate to pay approximately double for a planetary system of double the watts.

It is probably a good idea to receive several quotes, and if there are big distinctions ask why. And, as discussed before, don’t pick your solar panels based exclusively on cost; make sure it will supply sufficient energy to fit your needs.

5. Determine the needed size and Watts.

To begin, study your electrical energy bill. It will provide you with a great deal of helpful information to approximate your energy requires. Learn how many kilowatt hours (kWh) you use each day, month and year. When sunlight is optimal, a 100 Watt panel will create 100 Watts of electrical energy per hour. The majority of houses electricity needs can be satisfied with a solar system in between 1 to 5 kilowatts or 1,000-5,000 Watts. And in general, 1 square foot of solar photovoltaic panels in brilliant sunlight yields 10 Watts, but that can differ depending upon the type. Ultimately, when identifying the needed size of solar panels be sure that they will provide adequate electrical energy to meet or surpass your requirements.

6. Pick the Solar Panel Type.

There are 3 primary kinds of solar photovoltaic panels that are available to choose from and differ in effectiveness.

* Mono-crystalline panels are essentially one big solar cell. They are smaller sized than the polycrystalline panels.

* Poly-crystalline panels are comprised of numerous little cells grouped together which produce a little less efficiency than the mono-crystalline panels, and are potentially readily available for a lower cost.

* Amorphous (or thin-film) panels are bigger in size and need more area than the other panels. However, there are other significant benefits, such as a lower cost, versatility, flexibility and greater performances in the Midwest.

It ought to be noted that effectiveness just deals with the quantity of light that is created on brilliant sunny days. The thin film panels have the distinct capability to produce watts in low light and overcast conditions, therefore increasing its yield of watts over the exact same time for the other panels in less than optimum climates like the Midwest. Side by side contrasts in the desert expose something, however side by side comparison in a location that only has 4.2 hours of sunlight on average daily, the thin movie provides an unique benefit.

One need to also think about that the structure needed to mount the panel type vs. the thin film can include expense and future upkeep.

As there are different types of solar photovoltaic panel roofing systems available, there are likewise various types of installation techniques, such as a grid-tied system, which offers the capability to have more solar photovoltaic panels included at a later date.

7. Review the quote and planetary system specifications.

Read the fine print and be clear on all elements of the new solar panel system. Here specify points to review:

* Total Cost – Labor, setup and equipment.

* Projected cost savings – how many years will it take to pay itself off?

* Operational and upkeep costs

* Required permit costs, if any

* Solar system make and model – is it a trustworthy brand?

* Taxes

* Tax credits – 30% federal tax credit with no cap.

* Utility refunds

* Warranty – how many years? A lot of credible brand names will use a 25 year guarantee. If less, ask the length of time it takes to pay itself off.

Solar Panels stay a great option to reduce your energy costs, in addition to reduce your carbon footprint on the environment. Innovative solar panel style and technology is rapidly hitting the marketplace, so the future is intense for the solar panel industry.

Learn How to Save Money with Commercial Solar Hot Water Systems

Learn How to Save Money with Commercial Solar Hot Water Systems

Commercial solar hot water is not new. Large and small companies, hotels and resorts have been using it to save money for years now.

Not until recently have Commercial Plumbing Contractors pursued the solar how water niche. The demand use to be low but today we are now finding more and more licensed plumbing contractors being asked to contribute their knowledge and expertise in the solar hot water area. Whether it is a system for a new commercial project/facility or an eco-friendly addition, commercial plumbers are being asked to design/build systems for facilities from simple neighborhood laundry mats, public swimming pools to some of the largest name hotels, resorts and institutions. All businesses are looking to cut costs in their fuel energy costs and solar hot water is turning out to be a ‘hot’ and money saving solution.

All you really need today for effective solar hot water heating are two things: you need solar panels and you need a hot water storage tank. Solar panels are made from evacuated tube collectors that simply collect the solar energy from the sun, transfer this heat to the water and then into the copper coil heat exchanger located inside the hot water storage tank and from there it moves on to the domestic hot water system. This is one of the most efficient ways to use the energy of the sun for hot water uses.

The second component for solar hot water is the storage hot water tank. A storage tank can be designed and built for any type or size of project, regardless if it is for a new building or a pre-existing building. So long as you have a place that is flat, level and can support the weight of the water in the tank. Getting very large water storage tanks into existing buildings use to be a major problem but today we use a specially designed storage tank that comes in a collapsible form and can fit through a 19 inch door way and be set up in a matter of hours. This tank is state of the art and a one of a kind. This unique collapsible design is what makes it ideal for pre-exisitng buildings.

Major Types of Solar Power Systems

Major Types of Solar Power Systems

Solar Direct (or Day-Use Solar)
These systems do not have any storage batteries and are intended to be used only when the sun shines.
Without storage batteries, the power stops as soon as the sun goes away.soon as the sun goes away.
These systems are best suited for certain water pumping applications, venting fans, and certain electronics. Rare in application, they are very affordable and easy to install.

DC System with Batteries
These systems are great for small electronics that need to run day or night. Often times you’ll see these systems employed on highway sign lights, gate openers, and communication boxes. Simple and
affordable these systems have a wide variety of uses and are perfect for remote locations that require low voltage.

Hybrid Solar-Generator Systems
Most folks turn to a hybrid system for off-grid and back-up power applications. The hybrid system
generally consists of a PV array, a charge controller, a battery bank, an inverter, and sometimes a tertiary power source such as a wind turbine or a gas generator. This type of system is fairly complex and will require a high level of expertise to design and install. With the popularity of off-grid living, however, there are more and more packaged systems for people to choose from. These systems will provide power if the grid shuts down and can still sell power back to a grid if desired.

Heating your Home with Solar Energy

Heating your Home with Solar Energy

It doesn’t matter if you are building your home or remodeling, you can turn it into a solar energy home by making a few simple changes to your plan. If electric and gas become hard to manage you may want to consider heating your home with the sun. Solar energy is the heat that comes from the sun down to the earth. When it reaches the earth it spreads evenly but you may need it to go to a certain area like your home. How do you get that much sunlight to heat a home? It’s easy to do and takes a few extra steps to help get it started.

Building or Remodeling your Home
If you are building your home you have several choices to choose from regarding your heating source. If you choose to heat from the sun you need to build your home facing in the direction that the sun rise’s. This allows your home to get the most sunshine during the hottest part of the day. Buying solar powered glass windows allow the sun to come through and stay in the home without escaping back out. After the sun goes down your home is kept warm by the sunlight that came into the home during the day. You need to keep the door shut in order to keep the heat in and you also need to use insulated curtains on the windows at night so that the heat will not escape at night while you sleep. Make sure you don’t allow too many windows on the side of the house that faces the evening sun as it may cause the home to cool down quickly.

Remodeling your home to use the sun as a natural heating source is fairly easy to do. Although you can’t change the direction that your home is built in to face the morning sun you can still trap the sunlight that shines through and reduce the amount of time that you use another source of heat. You may want to consider building a sun room onto the side that catches the morning sun allowing it to heat up naturally and then install ceiling fans that will circulate the air into the parts of the house. During the day this may provide enough heat to maintain the warmth in your home. When remodeling your home, it will help to install solar power windows that are specially designed to attract the sunlight and allow it to come into the house but not let it escape. This is a natural way to heat your home.

Popular energy savers: solar hot water

Popular energy savers: solar hot water

Solar power is becoming more popular every day. This alternative energy source helps to save the planet by cutting down on the usage of non-renewable carbon based fuels, and it can save the energy consumer a significant amount of money on their energy bill. Another great benefit of solar power is that, once set up, the installation requires little upkeep, meaning it is pretty much maintenance free.

Solar energy systems generate electricity using the sun’s rays. The energy produced by various solar systems will supply electricity for the main property and any excess can be fed into the national electricity grid, reducing energy shortages.
Tremendous advances were made in solar technology since ‘global warming’ awareness arose and a worldly ‘energy crisis’ hit everyone’s wallet. People realized that other, more efficient and natural energy sources needed to be developed or enhanced.
One of the most popular solar power applications for residences, businesses or industrial use is solar hot water. This system can not only maintain a comfortable water temperature for swimming pools, but can also provide under-floor heating and space heating/cooling.

Solar water heating systems are generally based on thermal collectors. In addition, the system, which moves heat from the collectors to its point of usage, may require electricity to pump the fluid and a tank or reservoir to store the heat until it is needed.

A solar hot water system is economical and its basics are simple.
• Solar collector panels are installed on top of your roof along with a water storage tank.
• The sun’s energy will warm up the cold water in the collector.
• Once the water reaches a certain temperature, either by a pump or by thermosyphoning, it will be circulated to the storage tank.
• A water cycle is created when hot water leaves the collector and is being replaced by cold water from the bottom of the storage tank.
• Until it is needed, pre-heated water is conveniently stored in the tank.
• Because hot water rises just like air, heated water is taken from the top of the storage tank whenever you take a shower, or turn on your hot water tap.

Things You Should Know Before Investing in Solar Energy

Things You Should Know Before Investing in Solar Energy

There is no doubt that there are a lot of benefits in using solar energy. Aside from protecting the environment, you get to save a great deal of money. But before you switch to solar energy, here are a few things you should consider.

First, is your roof right for solar power? Most solar power systems can be installed as long as the roof is flat and made of material such as bitumen, composite shingle, cement tile, metal or tar and gravel. If this is how your roof is positioned, then there shouldnt be any problems.

The solar panels will be installed parallel to the roof surface. If you are concerned that the weight could be too heavy for your roof, dont be since this is very light and quite rare that you have to do some structural work before installing the system.

When you are looking for a contractor, find out how much it will cost to install the system. You should compare these first before you decide in picking the best one. But you should know right now that installing solar powered cells are a bit expensive. There are also no financing programs you can avail of. Your best bet if you dont have enough money is to apply for a home equity loan.

If you are planning to install this in a commercial establishment, the various loans you can avail of include the capital equipment loan, equipment secured loan, property secured loan or the SAFE-BIDCO energy efficiency loan.

Non-profit organizations may also avail of special loans for solar energy and the best one is through third party financing. In this case, the non-profit organization and the contractor will purchase the system and make use of the tax credits. The third party will then pass on the charges for the produced power to the non-profit and after the system has depreciated, this is sold to the non-profit at a discount.

The end result is that you pay for less than what you are currently paying for because it is maintenance free.
