Commercial solar
for Taranaki businesses

Before you commit

Four questions decide whether solar pays for a business. We work through all of them with you.

01

A large, unshaded roof is best. Smaller roofs limit your options, but many businesses still make it work. Shading needs careful analysis; if it only happens early morning and late afternoon the impact may be small. Check structural loading early, and how the fixing method affects your roof warranty. A new roof over car parking, or a ground mount, are alternatives, at extra cost.

02

Solar gives the best return to businesses with high daytime use, because you use most of what it generates on site. Ask your retailer for your half-hourly usage over the last year, and think about what could shift into the day once solar is in.

03

You will likely export some of the time, so check what you get paid for it. There will also be limits on how much you can export, set by your connection and the local network. We deal with the lines company on this, and it can change the best system size.

04

Higher power prices mean better returns. Look at what you pay at different times of day and year, and at the lines charges on your bill. How big those are, and whether they are fixed, can make a big difference to payback.
