Waiting for winter

Its summer & I'm riding regularly. The test will be winter when there's less light & I'll be relying on the panel to maintain the battery. I've noticed on overcast days it takes a while to show it's charging. Great service from Sportsbikeshop & Optimate who gave superb advice on connecting to the socket fitted to the bike.

Works well

It's been sunny since I received the solar panel, so it's perhaps been unrealistically ideal conditions in which to test it, but it's done a great job of keeping my bike charged during lockdown.

Works amazingly well, Optimate quality too

This works better than I could have hoped. It restored from well run down my wife and daughter's cars in two days of charging, and all "free" electricity, amazing. Should fire up a bike battery in no time. The read-out shows battery condition and charging progress plus an approximation of the light-conditions related charging efficiency. For me it works best with the 01 battery lead connected to the battery in place, no need to remove the battery), so you plug into that in just seconds. The croc clips would be better for a battery once removed from the vehicle. All in all, a top product and high quality too, being from Optimate/TecMate.

It works

Bought to supplement my Optimate 3. During the riding season I am unable to access electric sockets so a solar panel is brilliant. It is easy to set up and works a treat.

Excellent Solar Charger

Great bit of kit to maintain my batteries. I bought the 20w version as it is larger and more effective on winter days. Simple to use. Definitely recommend. Works well.

Did not work

After following all instructions and fitting the solar panel on my garage roof, it did not work, despite two days of strong winter sun. Alarm bells rang on opening the package as the sticky tape securing the box had been cut.

Excellent charger

Simple to install. Easy to operate. Slightly longer cable from charger to bike would help though (only get 1 metre).

excellent solar charger

I ordered the 20w version as I live in Scotland and the sun is in short supply at this time of year. This solar charger brought my bike battery up from half empty (orange) to full power (green) in just 2 days - its been in monitor mode ever since. I did needed an extension lead to fit it on my garage roof as the cable supplied is not that long. I'm very pleased with it - Another quality product from Optimate.

The new OptiMate Solar range features a smart charger-monitor which provides battery status information when charging and when the battery is at rest overnight. The OptiMate Solar TM-522 2 Amp smart charger-controller has a 4-LED panel for comprehensive information on charge progress and battery status.

OptiMate Solar charge kits are fully automatic. Mount the panel in a suitable location to receive maximum sunlight, hook up the charger-monitor to the battery and walk away. No more battery problems.

When the panel receives sun, the SOLAR CHARGE LED blinks confirming solar power is being delivered and one of the three battery status LEDs (SAVE, CHARGE, MAINTAIN) indicates charge progress. OptiMate Solar converts low solar energy to a high pulse charge which improves solar charge efficiency. When night falls or if the smart charger-monitor senses no solar power is being delivered it changes into a battery monitor with one of the three charge status lights now indicating battery status every three seconds.

The weatherproof solar panel includes corner mounts for easy wall or roof mounting. Each kit includes a high intensity poly crystalline panel with a 2m power cable, an OptiMate O-1 weatherproof battery lead, an OptiMate O-4 battery clamp lead and the outdoor rated OptiMate smart charger-controller (TM-522) with a 1m charge cable.
