Facts about solar energy help people understand the efficiency of solar power for heating homes, charging batteries and other appliances like solar flagpole light, free energy for homemade aeroponics system or home hydroponics and so on. It is almost impossible to make a valid choice for home energy systems unless we know about the available options. The applications of solar energy are multiple around the house, although most people have only heard of water heating with photovoltaic cells. But did you know that you can heat your swimming pool, power attic fans, computers and small appliances with photo-voltaic cells?
Sunlight is efficient for charging batteries, this is one of the best known facts about solar energy. The demand for solar panels is presently higher than the offer, although production has increased over the last years. And there’s no mystery about it: not all geographical areas and climates are compatible with the use of photo-voltaic panels. It is more difficult to get enough solar energy for all the electric appliances when you live in a cold or temperate climate.
In terms of statistics, some interesting facts about solar energy indicate that water heating consumes most energy of all. It takes around 30% of the total energy to heat water. The solar system as such consists of one or more panels with photo-voltaic cells, an inverter, a battery, a charge controller, the support structure and the corresponding wiring. The government presently offers tax credits and rebates for anyone who buys and installs specific types of energy efficient home systems.
If you are interested in more facts and statistical data about solar energy, you will see that for sunny climates, a 1 kilowatt home solar system can produce approximately 1,600 kilowatt hours in a year. In cooler climates with about 2 hours of sunshine per day, the number of produced kilowatt hours ranges at about 750 yearly. Even for average systems, the coal consume and the level of CO2 emissions is drastically lowered.
The optimal number of solar panels into an average home solar system is between ten and twelve; the panels should be oriented towards the North for maximum exposure. Solar panels have very extensive warranties, up to 20 years in the majority of cases. Yet, the system as such has a lower warranty span of about 5 years. The energy storage capacity and features vary according to the model of the panels. Cells collect sun energy and store it in batteries, or sunlight can be reflected, absorbed or insulated.
