Most of the people are daunted when they are asked to complete a solar panel installation. Besides the required Do It Yourself skills, you also need to know how to site the photovoltaic cells. There may be several risks involved. While working on the roofs, you have a danger of falling down. You are might be at a risk of electrocution while working on electrical connections.
You do not have to be discouraged or get scared. You can easily keep yourself away from any danger. Here are few solar panel installation tips to make your job much easier and safer. You must consider these points before you begin with your solar panel installation.
Suppose you are living in the north hemisphere. Then you can tilt your photovoltaic panels towards south in order to receive most of the sunshine throughout the year. In case your roof is facing south, then line the solar panels along the surface of the roof. Else you may need additional brackets to tilt the photovoltaic panels to south.
Many people think roof is the ideal place to site your solar panels. But there are exceptions. To find out the best place to locate your panels you need to do a through survey.
You must take into consideration the shading from plants and nearby structures. The amount of electricity generated may get reduced to a significant percentage with slight shading.
The sun changes its position in all seasons. This should be taking into consideration. Use a Solar Pathfinder to find out the location which receives the most sunlight throughout the year. Solar Pathfinder let you know the position of shadows at different times of the day and different seasons of the year.
If you roof turns out to be best location for installation. Find out the maximum load your roof can withstand. You must provide additional support to your roof, in case the panels are too heavy.
After finalizing the location, the actual work begin. Then you need to find the correct mount to fix them at ideal place. There are three types of mount namely pole, roof-ground and flush.
Flush mounts are used, when panels are installed on roof. It is the most easiest and cost effective way to mount small panels. They are metal brackets that support both the ends of a panel. These mounts elevates the panel a few inches away from the roof and create a space in between. This gap allows the air to flow through, cooling the solar panels. In order to maintain the efficiency of photovoltaic cells, it is important to have a moderate temperature.
Roof-ground mounts are grid like structures. They are generally used for larger solar panels. They could be installed on the roofs or on ground.
Pole mounts are used for supporting small, single solar panels.
Once they are fixed, you will have to run and connect the cables. The actual connections depend on the kind of system you want that is grid-tied or off-grid system.
I hope you found these solar panel installation tips useful. With proper installation, each panel could withstand strong winds and work efficiently for many years to come.
