Energy can bot be created or destroyed. Is energy limited in universe?

There seems to be an explosion of contactors and companies cleaning residential solar panels. Some as low as AUD$8/panel! Don't even know how anyone could make money at that rate...

Who's paying to get their solar panels cleaned? Does it really make that much difference? What's your experience been with these providers?

These Companies are greedy. If they did paid fair it seems like they're trying to beat everybody down into an hourly wage that is ridiculous now.

I also repair or complete botched systems for the finance companies. So I see a lot of terrible work, and meet a lot of unhappy customers.

I'm thinking about going solar in California, and trying to price it out. Based on my utility's rate plans (PG&E), I expect that the typical monthly cost will be something like $25 ($15 E-ELEC, $10 delivery charge) plus whatever I give/take to the grid.

One solar company mentioned that my utility essentially "taxes" solar arrays by charging a fixed amount per each kW of solar. But I cannot find anything online about this--either at the utility website, or searching via google. Can anyone who recently went solar in the Bay Area tell me what I can expect? Thank you!

Edit: Yes, I'll have a battery.

Attached image. A Big tall tree with the branches/leaves is blocking the production for ~3 hrs. Drops from ~4 kwh to ~0.5 kwh during that period. Any suggestions ?

Should I reach out to the city to trim it ? Can solar be a justified reason for trimming ?

Tree is located in a public space infront of next to next neighbor.

Does anyone know what these are called, or where I can buy them?

We are halfway to Pliocene-level warmth in just 150 years," says NASA scientist Gavin Schmidt. Are you ready ?

Is it any wonder so many people think solar is a scam? I get at least one call a week trying to sell me me a leased rooftop system from some shiathole call center. Half of them keep going with the sales pitch after I've explained to them I've owned my solar system since 2016.

I've not visited this sub for a few months, but what a shocker. So many bad faith arguments and short hostile comments.

Hopefully I'm wrong or it's a short term issue mods or time can fix.

Fairly simple question...if the exposed part of the anchor bolt (tower to foundation) is damaged in the process of removing a turbine, can the bolts be replaced? Or is the foundation permanently unusable? Specifically a Vestas V80...

This article has a lot of information about what is going to happen in the future with electricity and natural gas pricing. It explains how the various changes in demand for electricity in future years is going to raise prices. Seems like a good argument for installing solar.

I live at the edge of the Socal fire zone. We were evacuated a day or so ago but home now.

Our power was out several days and I'm now considering battery backup.

We are currently NEM 2. Installed base is 20 x 370 panels with Enphase gear.

We are currently a net exporter, sending 5.6 MWh to the grid with production of 11.6, usage around 6 Mwh. We have no charges with SCE the past two years.

I'm not thinking whole house for hours coverage as that would kill whatever budget I might have! The issue here most of the time is that SCE shuts down power during wind events as a precaution. Usually that's 6 hours, maybe 12.

Battery pricing has come down a bit, I imagine and the devices a bit more efficient. So looking for suggestions of products.

And being on NEM2, if I have to trickle charge the battery each day, therefore reducing the amount sent to the grid, how much power will be diverted that I will never get credit for? I'd rather not wipe out the yearly savings.

Any general overall cost figures will be appreciated. I know we are still able to get the 30% tax benefit plus stay on NEM 2 grandfathered. Will use our local businesses.

Thanks...
