A big thankyou to everyone involved with your organisation. You make life that bit easier with your products, back up and a wonderful web site. I have to thankyou also for the copies of the Good Times which have come with each order over the last year.

Just a quick thank you for your services. My package arrived 2 days after the order, well packaged, unharmed and works great!
Thanks for the drink coasters also - putting them to good use.

Grundfos SQFlex Pump System

It took approx. 2.5 days to fill the first 32,500 litre tank, appreciating day (light) pumping only, not bad!!
We thank you and most of all our cattle thank you. Kind regards

Sundaya j-Power LED Light Kit

I am most impressed with the 1 light kit purchased previously, and the drink coasters were a nice thought as well ;-)

G'day, as you might know I got a 2kw grid connect recently from you guys via Andy Colvin. It's in and fully operational and I must say, I am more than pleased with it's performance. . . I checked out I think every possible option before buying a system. . .; however, now that it is in and done, might I say, all I will remember for the next 25 or 30 years is what a sensational job that he did.

If only I had known the organised and professional manner in which he operates, I never would have bothered getting a quote anywhere else.

I cannot recommend Andy and his team highly enough. Quite, efficient and respectful. Rest assured I AM telling everybody this!

So thank you and I am so glad, to have finally, got my system from Rainbow and Andy Colvin Solar, good people to do business with!

I love your off-grid system sizer

You guys have done a FANTASTIC job with your solar system sizer. It's so much easier to use than anyone else's. As soon as I have our 'house' built I'll be ordering from you.

I wanted to write and let you know how great your site is. I am from Great Barrier Island, a small island off the coast of N.Z. We have no grid power supply, so rely solely on solar/generator for power. I [...] am highly impressed with the amount of extremely useful info you are offering for free on your site. [...] what i have read has already changed my thinking about designing a solar power system dramatically.
Keep up the great work! Regards

Dave, Thanks so much for your newsletter, I've been reading it for years and it's always terrific! All those past ideas I've squirreled away are now being used as we commence to build our very remote home near Ebor. You are a prince!

Dr John Magee

Thanks very much for all your help, and Peter's.

I have found my dealings with RPC to be always very positive. I have come a long way in understanding all this stuff, due primarily to Peter's book and his and your helpful comments and answers to questions.

I would certainly recommend RPC to anyone.

Matt and Gaire Stewart

My wife and I are very satisfied with Rainbow Power Company's information, supply and installation of our off-grid solar system last year.

Rainbow's after-installation training and information book have been very helpful in informing us on properly maintaining our system.
