One of my cousins told me she recently installed solar system with batteries and her electricity bill is too lower than earlier. I am also looking for solar options but my budget is slightly low to opt for batteries. Should I still invest in batteries or on- grid solar would be sufficient if I live in Delhi.

Hello, I know nothing about solar and refinancing but my parents used my credit to install solar panels 2 years ago witb Mosaic (now Solar Servicing) the interest is quite high at 11.49% so the monthly payments we are paying all goes to interest and nothing to the principal. I want to pay this faster. Please advice 🥲 I just don’t want to get stucked in this debt…

We are buying a house which gets tons of sun. No tree cover at all. There are panels on the main house and garage. The lease bill is $140 a month and $20 or so to be on the grid. What can I do to utilize the solar capabilities to the max? Im aware of certain tax advantages but not 100% clear on them and we have steam heat via gas and 5 zone split ductless so I'm thinking we get the house warm once real good in the winter with gas and otherwise run the ductless off the solar credits from the warmer months? (Ive heard we can roll credits til the greyer months.) Let me know if you have experience please. Thank you!

Hi everyone,

We are currently planning the installation of a PV system.

We will be using 38 × AIKO-A485-GRH48Dw modules (485 W each) – 18 modules in one string on the south-facing roof and 20 modules in one string on the north-facing roof.

I'm still trying to get my head around the inverter and battery storage options. My requirements are as follows:

• Home Assistant integration
• A low-voltage battery storage system (48 V) to keep costs down, as the budget is limited
• Backup power capability
• The ability to activate loads such as the heat pump's immersion heater when there is excess PV power
• Nice to have: the option to connect one or two plug-in balcony solar systems as well

Do you have any recommendations for an inverter that would meet these requirements, and which battery storage system would you pair it with?

After doing quite a bit of research, I've narrowed it down to two candidates:

• Deye SUN-20K-SG05LP3-EU-SM2 (20 kW)
• Hoymiles HIT-20L-G3S Hybrid (20 kW)

I'd appreciate any feedback or recommendations!

Finally got PTO on this system. NEM2 ESS with 28.6kWh

Just wanted to confirm, before switching my rate plan, that 18kpv battery charge + self consumption programming is capable of matching the following profile.

What is a good way for me to dry-run it for a couple days before switching? Mainly I'd like to know a good way to extract the data in an easy way to sling into Gemini to do the validation for me.

Hi all,

I have a 5 year old 9.99kw system (paid off) through Ion Solar in VA. Looking to get a battery installed. Talked to a rep for a while today, and he said they only do Tesla Powerwall. Told me $16,500 for one.

Any advice or guidance on what you all recommend? Or experience?

Thanks!!

Hi everyone im a solar installation apprentice in Nigeria,based near alaba international market,my goal is to become a solar design engineer but I'm having trouble finding professionals in this field nearby ,any advice or guidance on how to get started or connect with mentors will be gladly appreciated.

I have three bids which all recommend we roughly add about 30% excess capacity as we are considering a plug in hybrid or electric vehicle in the future. This is not the max number of panels that can fit but we felt like it was about right. Its a PPA style agreement for 25 years with a highly recommended company. I previewed the contract and can see that the performance guarantee is 90% of the original kwh after application of yearly degradation factor so a system that is designed for 10kwh has a performance guarantee in year 25 of 7900. Really? Is this what people are actually experiencing?

I have an existing system + battery, but no backup capability. I would now like to add that capability but prefer not to use the existing installer. I realize this presents warranty issues, but when I previously needed them for a warranty issue they were worthless - I ended up solving the problem myself with the help of Enphase. I had nothing but problems with them during the installation and their communication is terrible. Any risks I should consider before getting bids from other installers?

Hello - I have been considering solar for a while and am ready to go. We have a 2600 sqft ranch home that just eats electricity to the tune of 31,000 kwh yearly. Would love some feedback on this proposal. I feel good about the pricing and equipment, but would welcome any feedback. I am mostly concerned about panel placement. My state(Delaware) offers a cash rebate up to $10k which is why you see a spread between the numbers. In order to qualify, panels need to meet certain requirements for azimuth and TSRF. The first image was the original design. The panels on the front side of the house are ideally placed and will generate optimum output with a combined TSRF of 90%. However, the panels facing the back do not qualify because of the azimuth. Therefore, it was suggested that those panels be moved over to the right side as seen in the 2nd photo to earn the max rebate. Oddly enough, they qualify for the grant even though the TSRF(53%) is lower than the original placement(65%) because of the azimuth. I wanted to avoid this area as it's literally the only place that gets any shade. The trees arent on my property, so I can not do anything to improve sun exposure here. Does this placement make sense? Thanks in advance for any feedback or suggestions.

Hello, I'm wanting to set the time I discharge (export) my batteries to the grid. How do I do it?
