r/solar

Sounds like they wanna get them on batteries or something. This is the text message they got after the interaction.

>Your Sunrun appt is confirmed for [time and date] Your Sunrun rep will show you how solar + storage can help you take control of your energy. Get ready for your appointment by uploading your most recent utility bill: [link]

the link goes to a page called "customer presentation" with the time and date and a place to upload a bill. They haven't signed anything or uploaded a bill so at least they can't get got that way. Sidenote: every time i see the words "customer presentation" it's always about a timeshare, the most scammiest of scams, so that's got me real worried ngl.

They already have a SolarCity (now tesla solar) system with 17 panels on their home (but no battery) from 10 years ago with 10 years left on the lease. so idk what Sunrun can even do in this situation. the sun facing side of the roof is filled to the max, and every time i've called tesla to see if they can add powerwalls to an existing sytem they said that they can only add powerwalls with new solar installs. So the whole thing from sunrun feels a bit scammy. Or at the least the rep just lying to them.

anyone have experience with sunrun in SoCal (ladwp) area?

Suppose I've got 2 boxes of water in my yard. Both boxes have a large footprint but are very short, for example 10' long x 10' wide x 1' tall, so that only the top gets meaningful sun exposure and we can ignore the other sides.

Box A is painted black, using the most absorptive paint known to man. Or whatever other non-PV surface that will maximize the collection of heat.

Box B is perfectly covered with a solar panel. The solar panel is directly connected to a resistive heating element submerged in the water.

How much of a difference is there in the amount of water heating that occurs? Is it fair to say that if box B's solar panel is rated for 20% efficiency, then the water in box B will gain 20% as much energy as box A (plus whatever heat travels from the solar panel directly into the box, if they are thermally coupled enough rather than spaced out and casting a shadow on the box)?

We are having some re-model work redone. The electricians installed a 30A pre-wire ( guess they are required), and it can handle about 11 panels, which is great for us and has us at about 110% based on our current usage.

The solar installer wanted to do their own pre-wire to "future proof" it beyond 11 panels for $1500.

They said "-If you want to use the current pre-wire, your electrician needs to run the MC cable up through the roof where the solar panels are to be installed."

I took this as a good sign and suggested we do 11 panels and use the existing pre-wire. Then they responded back:

"   -To my knowledge, electricians will not penetrate roofs to run wiring/conduit as it is outside of their scope, and I will not coordinate a solar pre-wire unless my crew is doing the work in order to ensure that the work is done correctly and to the specs required."

Thoughts here?

In my previous home I had a trouble-free SolarEdge system and enjoyed near zero electrical bills most of the year. This helped sell the home! I've now moved South to Florida and would like to go solar again only this time with battery backup. I have an outbuilding with a large roof that's South facing and already wired that I suspect would be a good location as it sees little shade. Be a real shame if something happened to that one damn pine...

My previous system was on a standing seam metal roof - no exposed fasteners. Rails clamped down to the ribs but I had some fairly ugly conduit to look at - zero penetrations. The building I'm considering now has an asphalt shingle roof in good shape, the main house has shingles too but in less great shape. The outbuilding roof would probably be straightforward to replace with tin and I'm wondering if this might be a good idea. I'm new to the state but close enough to the coast to know that hurricane winds are for sure a possibility.

Is replacing the roof with metal a good idea as I'm considering a new system? I like the idea of not sweating shingles or roof penetrations but I'm not sure about uplift on clamps holding down panels. When my last install was done the county had never inspected solar on a tin roof and tried to tell me it had to be drilled down and manufacturer engineers had to get involved to satisfy them. Is this a bigger concern in Florida? Impact damage is another thought - should I consider buying a few spare panels when I'm getting quoted?

Paying a couple hundred bux a month for power after years of no electrical bill is a shock and knowing I'll be here for years this project is high on my list! Having battery backup for storms would be really nice, power on sunny days has even been iffy - don't get me started on Spectrum lol. I'm East Coast South of Cocoa FWIW and if the roof this is probably going on wasn't as high as it is I'd consider a DIY install I swear. Any other Florida weirdness I need to know about?

Thanks!

Anyone in Arizona was able to cancel their solar contract ? I have been seeing a lot of ads on facebook for solar cancelation. My setup was done by Freedom Forever and they filed for bankruptcy.

I wasn't told that a lien would be placed on my home. Looking for advice or experience feom people who successfully exited the contract.

I recently saw a video on how Utah approved the use and sale of plugin solar. These portable and cheap solar panels work by having a solar panel and micro inverter take solar energy and dispense it through a household outlet.

I'm probably out of my depth cuz I wasn't good at electricity in my physics classes, but how does the energy sent through the outlet get sent to other appliances in the household? Isn't the electrical in a house designed to send energy out to appliances, not take from them?

I've been reading a lot about vision 2030 and how all the projects have renewable energy quotas and the state itself wants to produce 50% of its electricity demand using renewables by 2030. So I'd love if one knowledgeable on the topic could help me with these questions.

1. Do you think especially with the climate in Saudi Arabia that its viable for solar panels? By that I mean the constant sand especially that it can be abrasive.
2. Is it a viable business idea if anyone has had exp with gulf governments?
3. How is the current global market and would I be able to import good solar panels at competitive prices? I've read about Pakistan's current solar system which honestly fascinates me so I was thinking if I could import the structure to the gulf market (roof top installations).
4. With the commercial electricity tariffs recently going up to 0.32 SAR/kWh, are private factories and commercial businesses in Riyadh actively looking for rooftop solar right now to cut costs, or are they still hesitating? I totally understand if you don't know but id like a insight on the idea.

I would also appreciate any help regarding risks I should be aware of and if I should move forward with this.

Thank you for reading!!

Looking for experienced solar installers.

I wish I were more educated before I pulled the trigger and installed solar panels. I have rooftop. Does the solar power generated feed my house directly? Or does it go onto the utility company’s grid and just offset the power I use? I think I know the answer but want to verify.

I'm looking to purchase a solar system in NJ. I thought about leasing and then realized the companies just get free money from incentives. I'd rather just get the incentives and own. Anyone know of companies in the NJ area? Thanks

Materials only I've been quoted $20k - $30k, with these being the installed quotes so far I'm thinking just hire someone to do it all. I DIY a lot and missed the tax credit years because I was procrastinating on doing it. What do you guys think?

I've got a large AC coupled solar array and just got an aPower 2 battery installed with the generator module. My goal was to use the Powerboost 7.2kw generator as the input to charge the battery in cases of extended outage.

Has anyone successfully done this? Have done all the AI researching and reading but hoped I can find someone who has done this to help communicate to the installer what needs to happen. I dont want to use an unsafe modified cable.
