It's better to get a solar system when you own a home. Don't overextend! If you have a mortgage and you need to finance your solar energy system, you could endanger your financial security.
Try to choose solar panels that can have their angles adjusted easily. The angle at which the sun hits the Earth changes throughout the year. This means that the best angle to catch the suns rays can be very different between summer and winter. Ideally you want to at least be able to adjust the angle of your panels twice a year, however if you can find some that allow adjustments four times a year (spring, summer, fall, winter) that is even better.
Know that solar panels do not immediately mean free energy forever. You need to be mindful of the fact that solar installations often carry a large up-front price tag. However, you also need to balance that with how much energy you can save over the long run, government incentives and the possibility of selling your excess power into the grid.
As requested here’s a breakdown of the cost in US dollars of the Enphase system with the Canadian Solar panels I installed in 2013. Keep in mind this price …
Consider a solar powered attic fan if you are not ready to make the full switch to solar energy. This type of fan features sensors that can turn on the fan at a certain temperature. This will remove heat and lower the cost of cooling. A good solar powered attic fan will help cool your house and not cost anything to run.
Gain an understanding of your own energy usage. Before converting to solar energy, it's vital that you have a good estimate of the amount of power that your home or business uses. In order to pick the right size, this information is critical. Look at your energy bills and invest in an energy monitor to keep track of how much power you use.
