Funny how oil companies such as BP were doing solar for a bit and then pulled out of the market?
I imported BP brand panels from the US 10 years ago to set up the system on our previous property. Only 215W rated panels which is pitiful compared to the 500W+ ones we have now. I think that like in EV (and battery) manufacture China has pretty much knocked other manufacture out of the park now which probably explains the apparent demise of BP and many others in this sector.
On a personal note we are looking like coming out of a credit balance with our electricity supplier for the first time since November as our PV has generated enough to charge both our EVs, run our home (including pumped water supply) and export more than enough to offset the power that we consume from the grid along with the daily supply charges. In effect our solar is making about $250/month benefit to our electricity costs so in effect the capex is equivalent to us having paid our electricity costs for the next 10 years forward based on ROI, and that's ignoring the certain electricity supply price increases that will occur in the next decade.
Yeah its funny looking back, I have an old dick smith catalogue and its quite funny looking at all the prices of these things.
Taking inflation into account, these things were expensive, like over $300 for a panel that was not even 200W
I see canon also had solar panels available, but they have since exited the market.
China is flooding the market right now with cheap panels at less than a dollar per watt.
BP at least had some foresight that they needed to diversify from oil and gas, but unfortunately it seems many oil companies, especially exon/mobil are going down the carbon capture path instead, i think most will just diversify into power generation as we are already seeing however.
Im looking at installing some on my garage roof, I could easily fit 5kw on my garage roof alone on the northwest facing side and about another 3.5kw on the north east side, that would significantly cut my power bill right down, i dont use an awful amount of power currently, so i think that would be plenty.
