Thread: Household Solar power installation companies?

I went through solarquotes.com.au to get three quotes 2 years ago. Ended up choosing the most expensive.

A very professional proposal but at a cost of $14,500 . they estimated power saving of $1500 per annum.

this is more than I am prepared to spend.
they say
[ Due to the shading issues from the tall surrounding trees, especially causing shading through the morning hours, you will need the more advanced SolarEdge inverter technology, with DC Power Optimisers behind every solar panel, which help to mitigate the shading issues, and therefore greatly improve efficiency and reliability. You will also have the advantage of being able to track the performance of each individual solar panel via an easy to use phone app. SolarEdge additionally happens to come with the longest and most comprehensive standard warranties of any inverter technology on the market, so it is the best long term choice.]

Sounds like you were getting a 7kwh system - maybe something smaller would be OK and be cheaper too?

I'd choose a smaller quality system over a bigger poor quality one.


Edit: or 5 - 6kwh with cheaper panels.

Look like nice panels. A mate of mine used to import cheap solar panels from China and apparently up to 25% were faulty out of the box. Caused him serious financial pain.

but at a cost of $14,500 . they estimated power saving of $1500 per annum.

Mmmm. About 10 years before you break even.

l'm waiting on solar quotes , 1 rang me but l had physio with me, l rang and emailed the guy back but he hasn't returned my call yet.
l did some back ground checking on their feed back and most reviews they had were from installations using GoodWe invertors and Jinko Panels both are Chinese. Never heard of those brands before, googling says they are large companies, but is the quality good?

I commissioned a Solaredge system today that we installed this week, good gear, but save your money and get a cheaper system, something closer to half or less than that cost after rebates.
