What People Had To Say

We looked at what people had to say about their Grape Solar purchase. 


No Grape Solar customers shared positive or negative experiences about their installed panels. Suffice to say we saw no negative reviews. 


Customers were either impressed by a good system and didn't wish to list small problems. No installation comments listed might mean customers were not sufficiently motivated to give feedback. It’s worth saying that no comments of problems to report could be a good thing.


Remember that your particular house or roof orientations may not be at optimum. That means the installed array size may need to be larger to accommodate the household load.

 

The PV system serves house electrical loads before the solar system output goes to the grid.

 

The Grape Solar panels look like most other on the roof. The warranties offered are industry standard. This investment at the price listed would able to offer savings return. With 265W Grape Solar there will be little to worry about if sized correctly. You'll be making few if any lifestyle adjustments.

​

Few customers made feedback about their experience with their panels. Disappointment from other brands' customers reflected their experience of not installing enough capacity. That meant energy savings were lower than monthly utility bills.

Our Recommendation

You may have ample roof space on your home.


Are you willing to sacrifice lower return-on-investment with a low efficiency array.


Grape Solar panels will be a cost efficient choice if you want a medium efficiency array. If you can fit enough panels on the roof you will meet your power needs. They come at a quite reasonable price per panel. Check that the installed price remains lower than equivalent or higher efficiency panels.


Be sure to compare the lifetime value of Grape Solar panels against other brands before you buy.

​

There are many Solar manufacturers’ panels available on the market. The Grape Solar panels stands out on price and it has fairly good test efficiency. This particular 60 cell Poly panel is a steady robust unit. It features the same sort of specification as others costing a lot more money.


The 265W Grape Solar panels are a good buying option.
