For a home owner, making the investment on a residential solar power system can be expensive. A simple grid tied-in solar energy setup can cost upwards of ,000. Luckily, the government is on your side. If you are planning to make an investment on green technology for your home, you can apply for solar power rebates.
How do you calculate the solar rebates? Here are 4 criteria that you have to consider.
1) Your residential geographical area - This will take into consideration statistical weather patterns in your area. This includes cloud density and frequency, average temperatures, air density etc.
All the number combined will give a measure of how much sunlight you can expect in your housing area in a given year.
2) The size and orientation of your solar modules - The best sunlight exposure comes from a specific roof angle. Different angle will yield different solar output. To enjoy the rebates, your solar modules have to be setup on specified angles.
If the solar panels are installed outside the specified angles, the government will reduce the subsidies paid out.
3) Shading issues inherent to the solar modules - To get this data, a special hemispheric reflector is used to measure the relative location and shading effects of trees, chimneys, mountains, other tall building etc. The device will tell whether the shadow caused by the obstruction will affect your solar module efficiency at any time of the year.
4) Your home solar energy system efficiency - This data will relate to you solar power productivity. The solar components manufacturers will define their system efficiency.
However, the final results will depend on where and how the solar collectors are setup. The government will give you solar power rebates based on energy production. You do not get the subsidies based on solar system installation alone.
