Please help me understand…
I live in Shalvey NSW (Endeavour Energy territory i am told). I initially googled solar and found solar101 which i thought was great, it gave me a brief general idea about solar. At the end it asks you if you want to get 3 quotes so of course i did. I received feedback saying there were only two reputable ones in my area. I thought that was odd given i live in Sydney but anyway moving along.
First two quotes were done based on my previous bills from our last house (before buying this one recently) and the area we live in. There was no site visit, just a google earth of my roof. They both recommended 10kw solar systems.
The first quote from Green Solar Energy was 30 x Longi panels and the Fronius Primo 5.0-1 plus Inverter 2 - Fronius Primo. No meter box upgrade required. Single phase quote. All that for $8500 and $8999 (two identical quotes, different price).
The second quote from Green Solar Energy was 28 x Longi panels and Fronius Primo 8.2-1. No meter box upgrade. Single phase for 7.5k
Then I got a quote from Red Giant Solar. 10kw system - Fronius Symo 10kw inverter and 20 x Qcells Mono 330w panels for $11,000.
The second quote from Red Giant Solar was 10kw system - Fronius Symo 10kw inverter and 20 x LG Neon2 350w panels for $13,000.
Red Giant were good for explaining to me what single and three phase meters meant as I had sent them a photo of my meter. They were great at responding to me initially. After looking through the forums here I had more questions and then found there were more solar installation companies that were listed on this site.
I called Western Sydney Solar. He called back and he was a little surprised that i was only given two options for solar quotes and even more surprised that both previous companies were trying to sell me excess products that I can’t have according to the electricity provider in my area ’ Endeavor Energy’. He explained that with a single phase Endeavour Energy we would only be able to benefit from 6.6kw panels and a 5kw inverter. He said companies can sell additional inverter ie 10kw but we would not benefit from it under Endeavour Energy. I was also told there is a limit of how many panels can be put on the roof? He was suggesting Suntek panels and Delta inverter were the better option based on his experience and quoted me roughly $7.5 - 8,000.
I feel a little nuts now. Can anyone please explain to me what all this means… if you can explain it all to me in layman’s terms. Clearly I’m not going to spend $9 - 14k on a product that I can’t use but i still want solar. I just want one that is useful and equally reasonably priced. No one wants to pay for a 5kw inverter or an additional 10 panels that you can use or benefit from.
thanks in advance.
