Can I Have Photo voltaic Panels On My Roof?


Is My Roof Appropriate For Photo voltaic Panels?

For a profitable photo voltaic expertise, the roof and panel relationship have to be an ideal match!

Roof Sort

In the case of photo voltaic panel set up, you will need to set up the kind of roof your property has.

Sturdy and sturdy roof tiles or supplies are finest. Extra particularly, supplies like concrete tiles or composite shingles.

Clay tiles should not as supreme, and you have to to seek the advice of a photo voltaic skilled who’s extensively skilled in set up on these kind of roofs.

Roof Age

A key piece of data to recollect is that photo voltaic panels have a protracted lifespan. How lengthy precisely? Properly, they’ll final successfully as much as 30 years!

Due to this, roof age performs an essential position. In case your roof wants changing quickly, you will need to guarantee that is accomplished earlier than any set up — a strong basis is essential!

Roof Angle

In the case of optimum solar publicity, the angle is all the pieces!

Your Roof Daylight And UV Publicity

The photo voltaic irradiation your roof receives is the crux of your photo voltaic panel placement.

A examine performed in Colorado checked out solar publicity on photo voltaic panels and confirmed the next:

Photo voltaic Panel Solar PublicityPV Technology
South and WestPeak of 1.2 kWh round noon
SouthPeak of roughly 1.4 kWh earlier within the day
WestPeak of simply over 1 kWh later within the day

Photo voltaic panels positioned in direction of the south and west will generate much less energy than these with solar publicity in direction of the south solely.

Panels dealing with west will generate much less energy and solely later within the day.

In different phrases, inserting your panels south will present you essentially the most publicity and PV energy, and earlier within the day, too (as proven within the picture under).

A roof with these directional and publicity capabilities is a well-suited one!

Water Drainage

When questioning, “can I’ve photo voltaic panels on my roof?” it’s essential to not neglect water drainage!

Generally when it rains, it pours, and the water should be capable of drain accurately.

If the set up of your panels wouldn’t trigger an obstruction for flowing water or divert the path, which can result in structural issues, then your roof is appropriate!

Beneath is a brief clip summarizing a number of details mentioned on this part.

How A lot Weight Do Photo voltaic Panels Add To A Roof?

The load your roof can stand up to is one other issue that can enable you decide whether or not you possibly can have photo voltaic panels in your roof.

Because the Nationwide Renewable Power Laboratory factors out, a PV system can add roughly 1.3 kilograms of weight (2.8 lbs) per 0.09 sq. meters (0.29 ft).

Nevertheless, this depends upon the kind of photo voltaic panels you put in.

The next picture from Kansas State College exhibits a number of examples of the load variations, with panels such because the Kyocera coming in at a whopping 16.5 kilograms (36 lbs)!

Please be aware: to transform from kilos (lbs) to kilograms (kg), merely the pound mass worth by 2,205
