Useful Tips

Are you planning to install a Hot Water System?

Involve your architect or your Sunpower sales representative at the design stage for guidance in choosing the right size system. It is important to consider the size of the property, the number of people using the system as well as the aesthetics.

If you prefer not to have the tank on the roof, you'll need a pump system. Your architect or contractor must be advised by Sunpower about the appropriate electrical and plumbing specifications to be incorporated into the designs. The roof designs must be able to accommodate the fittings in terms of leaving sufficient clear space around the panels and fixing them to the roof.

Remember to consider your plumbing system, as pipes running in excess of 30 feet to your kitchen or bathrooms will lose heat efficiency.

Here are some tips to help you get the best out of your solar hot water system

We have had a Sunpower water heater for 10 years and it works perfect. We have serviced our system on two occasions and each time the staff was very prompt and courteous. This is what I like about them. We got a great product and have loved it eversince then.
