Solar Panels for Homes

Are you tired of paying high energy bills? Ever wondered how much do solar panels cost or about the best do it yourself kits? Residential solar panel effciency for homes can produce enough power energy to justify the price of systems and installation. In our new going green generation, solar panels for your home are becoming more and more popular as our search for alternative renewable energy sources expands as we try to reduce our dependence on non-renewable resources.. As the gas prices go up, many Americans are starting to realize just how dependent they are of oil and coal. No matter where you live, everyone can benefit from residential home solar power systems price, especially now that it is more cost efficient. By Setting up your own DIY residential solar panel system, you can to help save the environment. Besides, when you set up residential home solar panels for your home, you are going to cut the cost of your energy bill as well. The two most applicable for residential use are solar photovoltaic (PV) systems and solar thermal systems. PV systems are comprised of approximately 20 panels that convert the sun's energy into electricty in order to offset a home's total electrical usage. Solar thermal systems convert sunlight into heat that can furnish your home's hot water needs.

How Do Home Solar Panels Work?

Solar power is the generation of electricity from sunlight. Sunlight can be converted directly into electricity using photovoltaics (PV), or indirectly with concentrating solar power (CSP). Photovoltaics were initially used to power small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a solar panel kit or photovoltaic array. Solar Panels for homes (PV modules or PV panels) is a packaged interconnected assembly of solar cells (also know as photovoltaic cells) made of a semi conductive material, often crystalline silicon. The solar panel is used as a component in a larger photovoltaic system work by converting sunlight into electric energy for commercial and residential home applications. Because a single solar panel can only produce a limited amount of power, many installations contain layers of panels, this is known as a photovoltaic array. The top layer is treated to be electrically negative, and the bottom is electrically positive. This causes electrons in the silicon cells to travel from the bottom to the top layer. They pass through electrical contacts in the top layer and are routed through a circuit, producing electrical power. A photovoltaic installation typically includes an array of solar panels, an inverter, batteries, and interconnection wiring.

Solar Panel Efficiency to Convert Energy?

The efficiency rating of home solar panels is fairly low, that is the amount of the suns energy converted into electricity. Solar Panel Efficiency can range from 15% to 40%, although there have been some recent breakthroughs in technology which has increased this to 80% with nanotechnology. When calculating how many solar panels for your home you will need, don't be too concerned about the solar panel efficiency rating of your DIY Solar Kit because photovoltaic panels are specified by their energy generating capacity. For example, 100 watt panel will output 100 watts of energy under ideal conditions. So if you are looking to produce 1kw per hr of energy you will need 10 x 100 watt panels. Home solar panel systems can produce enough electricity under ideal conditions to power the lights and electrical appliances as well as keep your home hot or cool. More of less depending on how many hours of sunlight per day your location gets.

What Happens if My Home Doesn't Get a Lot of Sunlight?

Most modern solar panel for homes are not completely useless. Many homes use both solar panel systems and traditional utility companies; while this doesn't cut your dependence on fossil fuels completely, it does make it possible to conserve energy while continuing to use all the appliances you're accustomed to. It is prefered to get at least 6 to 8 hours of sun a day.

How Much Do Solar Panels Cost?

As technology advances for photovoltaic panels, the prices come down in cost. Solar panel cost are currently selling for between $4 and $6 per watt of rated power output. A typical panel that you might install on your roof would be rated for between 100 and 300 watts and therefore will cost between about $400 and around $1500 or so. A complete solar power price also needs some other components and will have some installation costs and so the total installed solar system cost is typically in the range of $8 - 10 per watt of rated power. Most home sized systems are rated in the 1000 to 10,000 watt range and therefore cost between about $8000 and $25,000 dollars to install. Many states offer Renewable Generations incentive programs and tax savings that can reduce this cost by as much as 50% designed to encourage more people to invest in their own solar power generation array and sell the excess back to the power company. These systems will typically generate between about $300 and $2500 worth or electricity per year. Solar panels efficiency are expected to last between 30 and 50 years and so these systems will likely generate between $9000 and $120,000 worth of electricity over their life time in current dollars. This will vary widely though based on local electricity costs and may well increase greatly in the future if electricity rates rise.
