The most obvious reason is that they care about the environment. And electricity that is produced by huge coal and nuclear power plants harms the environment, while solar power does not. The only problem is that solar power is far less efficient than coal or nuclear power. Of course, this means that it is also more expensive.

But there are ways to install solar PV (photovoltaic) systems at an affordable price. This will inevitably involve getting your hands a little dirty and climbing up on the roof. So, if you suffer from acrophobia, you might want to stop reading now. Just kidding! The job is a relatively simple one and should only take a couple of hours.

The first and most important step is to purchase your solar panels at a good price on the internet. We recommend a small set that includes only a few solar cells to start. If the installation goes well and you are happy with your purchase, you can add more incrementally.

The only real question or concern when it comes to installing solar panel on your roof is where to position them. Ideally, you want to install the panels so that they receive the maximum amount of direct sunlight each day. If you are unsure about which part of the roof receives the most sunlight, there are a number of popular websites that track the progress of the sun.

Lastly, when it comes to the actual installation, all mounts must be secured with steel lag bolts that are bolted directly into the rafters. Therefore, you must know exactly where these rafters are before you attempt to install a mount. The easiest way to determine this is to have a friend or helper go to the attic and mark off all the rafters before you begin.
