Buying Solar Panels for your Home

There are a tonne of solar panels to choose from when you are buying solar panels. I am going to make it simple for you.

Follow two basic rules while buying solar panels :

The Solar Panel must be 300 watts or higher.
The Solar Panel efficiency must be 19% or more

Buying a 300 watt or higher Solar Panel ensures you get the newest technology and highest efficiency. And Why is that you ask?

Because 300 watt and higher solar panels are relatively new in the market. All the manufacturers have invested their latest and greatest stuff into making these new panels.

No going crazy about Mono vs Poly, Thin Film vs Crystalline : just follow these two rules and you will be buying the best solar panels for your home PERIOD.

Now lets look at your buying choices for buying solar panels that are 300 watts or higher :

Buying Super Premium Solar Panels

The two top Super Premium Brands are SunPower and Panasonic

These solar panels have efficiency starting at about 19% and going up to 21%. Compare that to Premium Panels which have efficiency in the range of 17% to 19%.

And, What is solar panel efficiency? Its just the amount of sunlight they are able to convert to electricity.

Remember, if you are buying Super Premium Panels, don’t pay a premium of more than 10% over Premium Solar Panel prices. Paying more for just a 2% jump in efficiency is simply foolish.

Buying Premium Solar Panels

Premium Panels which have efficiency in the range of 17% to 19%. And in my opinion these are much better value for money. I would always choose Premium over super premium.

But then I am a value buyer : I dont buy Beamers, I prefer the Honda’s and the VW’s.

The top premium choices for buying Solar Panels ( remember only 300 watts or more) in no particular order are :

Canadian Solar
LG
Renogy Solar
Silfab
Trina
Boviet
Recom

And dont be afraid to buy another solar panel brand if they have 300 watt rated solar panels with efficiency higher than 19%.

Flexible Solar Panels

Flexible Solar Panels unlike their cousins the regular tempered glass solar panels are predictably flexible to an extent and most importantly are far lighter.

Flexible Solar Panels use thin film solar technology which enables solar cells to be deposited on flexible material.

The advantages are their ease of installation, usually no screws and the ability to peel and stick some of them. The completely flexible varieties can even be rolled up. The downside to these panels are reduced efficiency compared to regular solar panels and much shorter warranties.

Flexible panels are great when you have constraints about weight; your RV or motorhome might not be ready for the increase weight of regular solar panels. If you have roofs which are curved or if you move around frequently, then flexible solar panels are likely to be your best choice. Of course you have to consider the higher prices of flexible solar panels ( about 25% premium) and the reduced efficiency and warranty.

Regular Solar Panels will be the better choice if you plan to install panels on a flat or pitched roof or if you have enough room on the ground to install regular panels. Some RV owners carry solar panel kits which they install once parked and thus they have access to more power than from flexible solar panels.  Since, you seem to have settled on the flexible solar panels based on your needs, here are the best of breed flexible solar panels sorted by brand and also the best reviews: Enjoy

  1. Flexible Solar Panels are such a convenience. I think flexible solar panels should be used everywhere. I guess the only negative about flexible solar panels is that they are slightly expensive. But I will always go for flexible solar panels. Thanks for the information.
