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.

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.

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.
