    What this does and doesn't tell you

    • Add margin for cloudy days. Most setups need a battery or power station in between.
    • Lithium-ion tool packs can short, overheat and catch fire if they're damaged, wired wrongly or charged on the wrong charger. Only use the maker's charger for the pack.
