Hi Deborahengler87,

Thanks for your question.

I guess you'd need to weigh up the different prices, quality and power production potential of the different systems to determine which would be the "best" solar panels for you in the long run.

In terms of quality I previously provided the following advice in an older topic -

That is a bit of a difficult question, as quality encompasses so many aspects and can be hard to measure in some cases. I would say though that a quality panel would have:
- a long warranty with good conditions.
- manufactured, distributed and installed by established, reputable companies, with reliable support available locally.
- some data/testing to back up its performance (over a long period if possible, e.g. showing low performance degradation over time). You may be able to find reviews of some panels.
- Certified by international standards bodies and CEC approved.

That's what I can think of off the top of my head. Others may have additional thoughts on this.

Best regards,
