Lets write about Denver solar energy for homeowners. The majority of today’s solar power systems do not required a lot of maintenance. Residential solar panels usually only require cleaning a couple of times a year. Serious solar manufacturers ship 20- or 25-year warranties with their solar panels. Technological advancements are constantly being made in the solar power industry. Innovation in nanotechnology and quantum physics has the potential to triple the electrical output of solar panels.

Certain solar cells require materials that are expensive and rare in nature. This is especially true for thin-film solar cells that are based on either cadmium telluride (CdTe) or copper indium gallium selenide (CIGS). Power density, or watt per square meter (W/m²), is essential when looking at how much power can be derived from a certain area of real estate of an energy source. Low power density indicates that too much real estate is required to provide the power we demand at reasonably prices.

In December 2015 the US Senate passed an extension to the 30% Renewable Tax Credit, extending this tax credit for a further 8 years. In addition to this federal tax credit, there are also rebates available in some jurisdictions at either the state, county or utility company level. If you use the solar panel calculator here you can see what rebates, tax credits and other incentives your house is entitled to based on its location, the utility company you are with and the number of solar panels you need to power your home.

Solar panels (also known as photovoltaic panels) are installed on your home. The solar panels convert light (photons) into electricity (voltage). Each panel is connected to a microinverter that changes the electric current from DC (direct current) to AC (alternating current). Each microinverter operates independently of the others so that if one stops working your system is still generating maximum power. An alternative to being tied to the utility company is an off-grid solar panel system. An off-grid system is similar to a grid-tied system with the exception that all the solar energy that is generated is stored in solar energy battery banks in your home. A charge controller sits between the batteries and the solar cells to ensure that the batteries do not overcharge. With an off-grid system you are 100% electricity independent.

The typical solar panel installation takes one to three days. Obviously, larger systems will take a little longer. After the solar panels are installed the utility company will come out to change out the electric meter. Depending upon the utility company, it can take one to three months for the utility company to do their part and turn on the solar energy system.

The typical time need to see a return on investment is going to depend on your specific installation. The direction your roof faces in relation to the amount of sun it receives, the number of solar panels you need and whether you install an off-grid or grid-tied system will determine how much money you save each month and how long it takes for you to recoup your investment. A typical solar panel installation takes anywhere from 3 to 7 years to see a return. See extra details on Solar energy, making the world a better place.
