The average homeowner can reduce or eliminate their annual electricity bill by installing a solar power system. They will never again have to worry about another electric bill if they install a properly sized solar panel array. Some homeowners, though, encounter problems that prevent them from getting the return on investment that they had hoped for. However, many of these issues can be overcome with recent innovations and improvements in solar technology. These improvements apply with both a purchased solar panel and a DIY solar panel.

Their home’s orientation to the sun is probably the largest concern for most homeowners. For solar power systems to operate at peak efficiencies, a home has to have a roof that faced south if they were located in the northern hemisphere. As the sun travels across the sky, a southern exposure ensures that the solar panels get a good amount of sun through the day. This was a critical concern in years past as older solar panels were very specific in their need to have a constant sun exposure for most of the day to generate power. If their positioning was even a little bit off, it could have a major impact on the amount of power they could generate

More efficient solar cells in modern panels solves this problem. These newer solar cells are not only able to generate larger amounts of power from the same sunlight as older cells, but they can also tolerate the sun hitting them at a more severe angle as well. This wider tolerance means these newer solar cells can be used in many locations that were not good choices for the older cells. For installations with less than perfect alignment, these newer solar cells are ideal. These modern solar panels will produce more electricity when there is dimished sunlight, like on cloudy days, and also in these situations that are out of standard alignment with the sun. Because these newer solar panels don't need to pointing directly at the sun all the time, they don't need to be turned during the day like a lot of older panels. This makes them well suited to a homemade solar panel install.

This is quite an advantage over older panels that had to have a lot of consistent sun in order ot produce electricity. Because of this, older panels were inactive when the sun was rising in the morning and setting in the late afternoon. Even though there was sunlight, they could not produce power because the sunlight was not of a sufficient level to get them started. The newer solar panels can take advantage of these lower levels of sunlight and will produce power proportional to the level of sunlight available. This means they will produce their maximum output during the day when the sun is brightest and will still produce power in lesser amounts when less sunlight is present. Because they are able to produce more power for a longer time each day, these newer solar panels can produce more total power each year. The additional power this will provide can add significant savings and allow the homeowner to justify a solar power system for their home.

A solar power system is one of the best ways to increase the resale value of your home. No matter whether you supplement the electricity provided by the power company or supply all of the electricity needs of your house, a solar power system will definitely increase the value of your home. A simple diy solar charger will get you started in the right direction.
