FAQ of rooftop solar Racks

How much space is required on my rooftop for 1 kW of rooftop solar rack?

1 kW of solar power plant requires approximately 100 sqft or 10 sqm.

Can I run all my loads entirely on solar power from my rooftop?

While in select cases a rooftop solar power plant could power most or all your loads, in most cases, it will be difficult. Depending on the type of building (residential, commercial, industrial) and the extent of rooftop available, solar from your rooftop could power anywhere between 20-50% of your total load requirements.

If solar power from rooftop cannot supply all my load requirements, how can I make the best use of rooftop solar?

One of the best ways to use rooftop solar power plants is to use as a grid-tied rooftop solar power plant. In this case, even if your rooftop solar power plant is not able to meet all your power requirements, the deficit can be met from the grid.

1.Why are solar panels mounted on sepcilally inclined rooftops?

Tilt angle is  necessary . the solar rack can make the solar panels to convert more sunshine into power.

The angle your solar panels are mounted at will affect how much power they generate for you.

Generally speaking, (unless your roof is flat) the pitch of your home’s roof is going to be the angle your solar panels are mounted at.

2,What if you have a flat roof?

If your roof is totally flat, then I strongly recommend mounting the solar panels at an angle of at least 10°. This is really important because it will allow any rain to run off the modules.

If the rainwater pools on the surface of the solar panel, it is more likely to eventually get through the panels’ seals and into the solar cells themselves. If this happens it is game over for the panel as you will get an earth fault and need to replace the module. Many panels have a warranty condition stipulating they must be mounted at at least 10° from horizontal, so failure to do could void your warranty.

Don’t listen to anyone that tells you to have the solar panels horizontal and just add a panel or two to make up for lost efficiency. Horizontal panels are asking for trouble down the line. They will also get a lot dirtier because they will have very little ability to self-clean through rain, so you’ll need to manually clean them more often; which is time consuming – and time is money. Added to that, getting up and working on a roof is a safety risk.

For these reasons, if you have a flat roof, most good installers will add the option of a tilt frame to their quote.

3.what's the difference between a  ground  mount and rooftop solar rack?

Roof mounts are less expensive because they use your existing roof structure as a foundation. They also take up less room on your property. Ground mounts take up more space, but they’re easier to access for installation and repair. They also give you greater control over the orientation of your array to maximize production.

Roof mount systems affix to brackets on your roof, while ground mount systems are built into a foundation at ground level or dig into the ground by ground screws.
