With payback periods of at least 10 years. So I'd hold off the batteries for now. In any case, your EV may become your mobile home battery, as we move to V2G (vehicle-to-grid) & V2H (vehicle-to-home) technology. The battery in EVs much larger than home batteries. Re: Solar Panel Installation 4Aug 04, 2022 1:38 am ddarroch Installing 32A power circuits (if your not 3 phase) in the garage, as we'll be driving Evs soon. That's great information ddarroch, referring to your whole post, but I didn't understand the above comment. Are you saying 32A circuits for EVs are not required if you have 3 phase?

Are you saying 32A circuits for EVs are not required if you have 3 phase?[/quote:36to5jl1] Firstly, I'm not an expert. But a normal, single phase 10A power point will charge at a rate of 2.4kW. So a 60kWh EV battery will take 25 hours to fully charge from flat to full. Too long for most people. Use a single phase 32A plug, & you can charge at 7.6kW. That 60kWh battery will charge in just under 8 hours. So acceptable for many people, whether charging overnight, or with solar on a sunny weekend. Again, not an expert. But 3 phase power will charge 3 times faster. So a 10A 3 phase plug will charge at 7.2kW. So a very similar rate to 32A single phase. Recharging in just over 8 hours. So acceptable for many people. Sure you can get a 3 phase circuit at 32A for very fast charging at 22kW. Recharging the 60kWh battery in under 3 hours. But at this stage, many cars won't recharge at 22kW AC, some limited to 11kW I believe. There would be very few residential solar systems that could generate power at 22kW, so if charging at this rate, I'd expect some imported power to be needed. Not an expert on chargers in any way, & don't know if they can be set up to only charge at rate using excess solar power. Also don't know the cost of chargers. Whether 3 phase chargers cost more, or chargers that charge at higher rates, or if there's smart chargers that can be set up to just use excess solar. 32A 3 phase may be good for future proofing. It may be good to have very fast AC charging when required. But even 10A or 15A 3 phase will be fast enough for many people on most occasions. While 10A or 15A single phase will be too slow for most people. 32A a better idea for people limited to single phase power. Re: Solar Panel Installation 6Feb 21, 2024 9:27 am kumar2015 What would be the better option - Is it better to install solar on Duplex units from builder (3kw $3500-$5500 per unit) or hire a solar company later to install this ? I know it can be little bit lesser, but heard many stories about installation on the roof and damaging it, etc. Please suggest the nominal price range for 3kw instllation with panels, invertors, batteries. $3500 for a 3.3 kW setup? Your builder is applying a markup of about 100% and is having a lend of you. For that price you'd be able to install 6.6kW easily Re: Solar Panel Installation 7Feb 21, 2024 3:02 pm Althom kumar2015 What would be the better option - Is it better to install solar on Duplex units from builder (3kw $3500-$5500 per unit) or hire a solar company later to install this ?

Re: Solar Panel Installation 8Apr 23, 2024 12:35 pm Deciding whether to opt for solar panels from the builder or hiring a solar company later is a tough call. While the builder's option seems convenient, there's always the risk of potential roof damage during installation. On the other hand, hiring a solar company might offer more flexibility and potentially lower costs. It's worth exploring both options and getting quotes from reputable solar companies to compare prices and services. Ultimately, finding the right balance between cost, quality, and convenience is key.
