The Sun is simply one big battery for us. All life on earth is supported by the sun. This amazing resource radiates energy and provides us both heat and light by fusing hydrogen into helium at its core. We call this solar radiation. Only about half of this solar radiation makes it to the Earth’s surface. The rest is either absorbed or reflected by clouds and the atmosphere. Still, we receive enough power from the sun to meet the power demands of all mankind — millions of times over. Solar energy—power from the sun—is a vast, inexhaustible, and clean resource. Solar is a safe alternative which can replace current fossil fuels like coal and gas for generation of electricity that produces air, water, and land pollution. The main advantage is that it is a renewable, clean source of electricity. Solar power is also scalable. This means that it can be deployed on an industrial scale or it can be used to power a single household. When it’s used on a small scale, extra electricity can be stored in a battery or fed back into the electricity grid. Overall, the sun gives off far more energy than we’ll ever need.
Photovoltaic and solar-thermal panels generate free electricity by converting sunlight into electricity or transferring the sun's heat to heating and ventilation systems. The use of solar panels to generate energy provides many benefits, which include reductions in the costs associated with generating electricity. Solar panels also provide pollution-free power sources and afford new levels of independence to energy consumers.
Determining how many solar panels you’ll need for your home means first knowing what your goals are. Do you want to minimize your carbon footprint? Maximize your return on your investment? Save as much money as possible? Most people want to save money while minimizing their environmental impact. To calculate how many solar panels you need, you need to know the following: how much energy your household uses; your roof’s usable surface area; the climate and peak sunlight in your area; the wattage and relative efficiency of the photovoltaic (PV) panels you’re considering; and whether net metering is available.
Why Choose Solar Panels for Your Homes?
Renewable - Solar panels produce electricity by transforming the continuous flow of energy from the sun to electricity. The sun provides more than enough energy to meet the whole world’s energy needs, and unlike fossil fuels, it won’t run out anytime soon.
CO₂-free - No harmful emissions are released into the air when electricity is produced by solar panels. No greenhouse gas emissions are released into the atmosphere when you use solar panels to create electricity. And because the sun provides more energy than we’ll ever need, electricity from solar power is a very important energy source in the move to clean energy production.
Low operating costs - The photovoltaic process that transforms sunlight into electricity doesn’t require any fuel and has no variable costs. After solar panels have been installed, operational costs are quite low compared to other forms of power generation. Fuel isn’t required, and this means that solar power can create large amounts of electricity without the uncertainty and expense of securing a fuel supply.
Reduce Your Bills – Generate free electricity using solar panels and reduce your energy bills because solar panels can provide up to 50% of electricity.
10 – 15% Return on Investment – Solar panel offers long term savings for household and the average system pays up to 15% return on investment. Sunlight, or solar energy, can be used directly for heating and lighting homes and businesses, for generating electricity, and for hot water heating, solar cooling, and a variety of other commercial and industrial uses. Most critical, given the growing concern over climate change, is the fact that solar electricity generation represents a clean alternative to electricity from fossil fuels, with no air and water pollution, no global warming pollution, no risks of electricity price spikes, and no threats to our public health.
