Like me, you could store that power all week in a large battery bank and have around 7,500 Wh (1,500 Wh 5 days), or 7. 5 kWh, in your battery bank for the weekend. But this method isn't common for off-grid sizing, and you'll see later that costly batteries and other parts indicate you're better off with more panels instead.

With a need to bank about 7. 5 kWh of power every day, and with 5 hours of usable sunlight per day, you'll need 1. 5 kWh of photovoltaic panels (7. 5 kWh 5 h). If you use the Suniva panels that we like, you'll end up with six 280 W panels, which will offer you around 1.
You might probably find some more affordable panels, however we'll call that $1,900 for your spending plan. Made by a trustworthy firm with a strong service warranty, this module supplies good output without a premium cost.

My choice, the Midnite Solar Kid, isn't rather up to your task. The charge controller I use for my existing system is a Morningstar TriStar TS-MPPT-30, and that design needs to serve you well; it's presently offered for $330. From your charge controller, the power will travel to your battery bank.
This is where your weekend use gets tricky. If you wish to be able to utilize power when the weather has actually gone to pot, you'll need your whole usage7. 2 kWhsaved up.

To keep your batteries in good shape for several years, you ought to prepare to utilize about half their capability. So this 7. 2 kWh requirement just became a 14. 4 kWh battery requirement. In a 12 V system, that's 1,200 Ah (14,400 Wh 12 V). Yikes. You'll need 6 of these Rolls Surrette batteries comparable to mine, costing as much as $2,200.
If you're budget-conscious, do not even consider going to lithium-ion batteries just yet. The Tesla Powerwall, which keeps making headlines, costs $3,000 wholesale for 6. 4 kWh of capacitythe price will not come down substantially for a couple of more years. Fortunately, batteries are a simple element to update as your budget plan allowsyou can add additional lead-acid batteries in a year or 2, and no other devices will require an update.
Each. Let's begin you with four, plan to be miserly, and call it $1,500. solar powered appliance. My batteries power a reconditioned Magnum Energy MS2000 Inverter (the left half of the giant white block) that's mated with a partly prewired Mini Magnum Panel (the right half of the white block) for a cleaner install and less fuss.
If you're budget-conscious, do not even think of going to lithium-ion batteries right now. Your inverter will turn all that stored-up DC power into Air Conditioner power so that you can utilize standard family electronics. The maximum output of the inverter will be the optimum you can run all at as soon as. You say you use 300 W per hour, however if that's sometimes a 1,500 W microwave and often a 2,000 W mixer, you need an inverter to match that optimum.

I use a 2,000 W Magnum inverter, and I enjoy the quality and accessory components, however even the business's 1,000 W (and $1,000) model may be overkill for you. If you have space in the spending plan, I 'd absolutely recommend it. To keep things basic, though, you might choose a more economical design like this 1000 W ($ 400) example from Cotek, though I do not have any experience with that company's gadgets.
Sometimes those work terrific; my old one's worst problem was an obnoxious but peaceful buzz that persisted no matter what I did.

If your cabin is subject to structure licenses, you'll need to factor those in, and possibly the expense of an electrical expert.
And with planning, creativity, and input from your vendor, you can discover methods to begin small and scale up without squandering money on equipment you'll grow out of in a year. solar powered appliances. Someone equipping a full-time house will want to purchase higher-end gear, however you'll need to decide what the goal is today versus five years from now.
