Solar panels are becoming a good and an increasingly attractive source of renewable energy for the home. This is due to three main causes; specifically, the rising costs of conventional energy, the falling prices of improved solar panels for homes as well as incentives offered by governments that make green energy an attractive option.

In the U.S., more than 10,000 homes are powered entirely by solar systems. Another several hundred thousand homes use solar panels to partially meet their energy requirements. That results in significant savings on energy bills. Respectively, the use of non-renewable resources like fossil fuels is reduced, which amounts to less environmental pollution.

The cost of installation for a home of a typical family can be $18-20 K if carried out by a professional installation company. These high costs prevent people from using solar panels. However anybody can save money on installation costs through tax credits and state rebates. Moreover,you can do it yourself, and then the cost would only be approximately 30 % before tax credits and rebates.

You can have 2 choices: a stand-alone unit which requires a storage battery or a grid-intertied unit.

A worthwhile improvement to your home is to convert to grid-intertied solar panel system. Planning ahead is the main prerequisite of successful conversion.

First, calculate the amount of energy you will need based on historical consumption. You should select the right size of your solar panel system. An oversized unit will generate more power which you could sell to the power company, but you can only receive credit for it and not cash.

Then, determine if your home is suitable for a solar energy system. These factors are to be considered:accounted for: available space on the roof, house orientation and climatic conditions. A good estimate of roof space is 80 to 100 sq. ft. per kW. A building has to face south for the solar energy system to be efficient, and should be free of objects that may get in the way of sun rays.

Though it is possible to install the solar panels on poles, panels are as a rule mounted on the rooftop. With the help of steel bolts, the supports are attached to roof rafters. The panels are then attached to the supports.

Solar panels are readily available in the market. There are vendors that sell their panels on the web, but I would not recommend that you purchase the kits from them unless you have prior experience with installing them.

Typical set of hardware you will need for a batteryless grid-intertied system includes: solar panel units, utility-interactive inverter, power meter, roof mounts, a couple of heavy duty safety switches, wirings and cable conduits. A DIY kit for a 1-kW system would cost you a little over $3,000.

If you are not experienced in this area, you have to select a reputable vendor who is known for quality service. It is just sensible to purchase DIY kits with accompanying installation manual that at least has a good number of illustrations. The vendor should preferably have contact telephone number, and better yet, could provide an engineer in case you need advice. Or if you are a lucky guy and have a friend who had previous experience with installing home solar panels, then ask him to help you in the buying of the hardware as well as in the installation.

Many individuals have shown that renewable energy can save one both money and the Mother Nature. With the abundance of improved, affordable solar panels for homes and businesses, solar energy is the best option for the majority of people, so go back to that home improvement project: install a home solar power unit.
