Reply to comment by Surur in Rooftop solar trumps all fossil fuels as renewables smash more records on main grid [Australia] by EnergyTransitionNews

I figured this out after talking to a few people on hear who seemed really angry that solar was crazy unaffordable. From my perspective it's expensive, but the panels are the cheapest part and the reduction in energy means they should pay themselves back double over their life time.

I got 2.2kW worth of panels added to my roof. The panels cost about £700 ($750). The inverter and other equipment was another £1500. The scaffolding was £700, and the installation was £1200.

£4200 total ($4500) and halved our energy bill!

Just had a quote run here in Texas. $45,000…no storage battery included.

For an amount comparable to 2.2kWh!? That's insane!

19kWh system, 49 panels.

That's about 10x the size of mine, so actually not too surprised it's 10x the price!

To have that much solar power on my house in the UK I think I would need to register as a power station, if I wanted to also connect and input to the grid! (Don't hold me to that, it's just anything up to 5kW has a really simplifying process and no planning permissions or needed or anything).

In the UK average houses only really need 2-3kW system, which would basically meet all needs in the summer but not really touch the sides of usage in winter - we get so little sunlight in the winter it's not even worth trying.

It's very, very rare for a residential property to have above a 5kW system.

But then, we don't really use cooling and we tend to use natural gas for heating. So while we only use 10-15kwH of electricity per day, we use a lot more in natural gas for heating over the winter.

Call project solar. They seem to have the best rates in our area of TX. We had quotes from 5 companies and they were the best quote by far. I found Project Solar by researching on the solar Reddit page.

I can’t get my head wrapped around it just yet. According to their calculations, for 75% offset I’d still be looking at 25k over 20 years, not accounting for local hoa regulation issues, not accounting for system standard degradation over the loan term, unable to get data from the providers myself and are locked into their app, not accounting for an increase to my insurance policy.

The list of issues really grows large for a basic setup.

Well HOAs are legally bound to allow for solar installations (Section 202.010(b) of the Texas Property Code states that “a property owners’ association may not include or enforce a provision in a dedicatory instrument that prohibits or restricts a property owner from installing a solar energy device.”). Most warranties on our quotes were 25 years - the equipment under this warranty is guaranteed to produce around 90% on the guaranteed starting production. Not trying to talk you into anything. Just made sense financially in the long run for us.
