Every November, portable power stations and solar kits show dramatic percentages off. Some are genuine, many are not. Here is how to shop.

Step 1: know the real price

Many brands raise list prices before sales. Use a price-history tool for Amazon listings, or note prices on the manufacturer’s site in October. A fair Black Friday discount on a solar kit is 10-25% off the recent street price; on power stations and batteries, 25-40% is common.

Step 2: price per watt and per kWh

• Kits: divide price by watts. In 2026 US kits typically ranged from about $1.00 to $2.00 per watt; small certified kits cost more per watt.
• Batteries: divide price by usable kWh. Compare with the same brand’s non-sale price and competitors.

Step 3: check the bundle

A bundle of a power station plus panels plus accessories can look like a bargain while including accessories you do not need. Price each item separately.

Step 4: certification and legality

A cheap kit you cannot legally connect is not a deal. Check your state’s rules and the certification list. In the UK, confirm compliance with the Interim Product Specification.

Step 5: return policy and warranty

• Is the return window extended for holiday purchases?
• Who handles the warranty, the brand or a marketplace seller?
• For batteries, is the warranty based on years or cycles?

A worked comparison: is this deal real?

Suppose a listing shows an 800 W kit “was $1,399, now $899 (36% off)”. Before buying, run four checks:

1. Street price. If the same kit sold for $999 through most of October, the real discount is $100, or 10%.
2. Price per watt. $899 ÷ 800 W = about $1.12 per watt. In 2026, US kits typically sold for roughly $1.00-2.00 per watt, so this is good but not exceptional.
3. Legal fit. Does the inverter’s maximum AC output fit your state’s cap, and does it carry the certification your law names? A kit that cannot be legally connected is not a bargain.
4. Payback. At 600 kWh used a year and 22 cents per kWh, the kit saves about $130 a year: a payback of about seven years at $899 versus almost eight at $999.

A ten percent real discount shortens payback by months, not years. That is worth having, but not worth buying the wrong product for.

Batteries and power stations: price per usable kWh

For storage, divide the sale price by usable capacity. A 2 kWh battery at $1,000 costs $500 per kWh; a 1 kWh unit at $600 costs $600 per kWh. Then check the cycle rating, the warranty length and standby draw, because a cheaper battery that uses 20 W around the clock loses about 175 kWh a year. Our spec sheet guide shows how to compare them.

Timing tips

• Note prices in October so you have a baseline.
• Manufacturer stores and large retailers often match each other; check both.
• Check the return window. Holiday purchases often get extended returns, which is useful if your landlord says no.
• If your state’s law takes effect in 2027 (Virginia, New Jersey), buying in November and installing when the law allows is reasonable, as long as the product will qualify.
