If you're thinking about installing solar power at home, it's essential to configure your system to meet your energy needs—especially when it comes to something called 'baseload.' This is the minimum power required to keep everything running smoothly, even during those tough winter months with lots of cloudy days. For instance, if your home consumes about 1,250 kWh in December, and you also need to charge an electric vehicle, you'll want to design your solar setup—like panels, inverters, and batteries—so that it consistently produces enough power. How can you accurately determine your baseload requirements and design a system that will always meet this demand?

The first thing you need to clarify is whether your system is on-grid or off-grid. Going on-grid tends to be easier because you can rely on your utility to buy back excess power. As for guaranteeing production, one common strategy is to oversize your solar panel array so you can use some of that excess power when needed. Just make sure you’re aware of the costs of potentially coming up short—like having to pull from the grid occasionally. I've used the PVWatts site to estimate production based on your setup, which can help a lot!
When planning, consider whether you're looking at your highest or lowest energy usage. For example, my home uses 3,683 kWh in summer (peak demand) and drops down to 703 kWh in winter. I suggest you prepare for a blend of both by having a solid backup solution—maybe a day’s worth of power for tougher weather. However, weighing the insurance and regulations, especially in certain states, could impact whether going solar really makes sense financially. I'd look into offsetting the higher uses first and possibly going solar for just certain appliances like the washer and dryer.
For sure! It’s all about finding that sweet spot where your energy needs meet your budget.
I think taking on baseload production for 5 days to avoid using grid power isn’t entirely necessary. With low rates for exported energy, do you really want to invest heavily into a setup that may not even pay off? Start small, assess your needs, and only scale up if it's justifiable. And don’t stress too much about future-proofing; technology always improves and prices could drop. For instance, I just set up 42 kW of panels and even on cloudy days, I still get decent output!
Yep, I just transitioned to off-grid living, and it’s impressive how well my 42 kW of panels work, even with some cloud cover. Planning your setup really makes a difference!
Totally agree! It makes sense to start small if your budget is tight. Test the waters with a few panels and expand as needed. Plus, you'll learn more about your actual consumption that way.
