\n

Solar panels, smart charging and a battery are often presented as the ideal combination for sustainable mobility. In practice, it does not always pay off.<\/p>\n

The energy flow<\/h2>\n
\n
Production<\/span>Solar panels<\/strong>Generate power during the day, even when the cars are not plugged in.<\/span><\/div>\n
Buffer<\/span>Battery<\/strong>Stores that energy and releases it when the cars return.<\/span><\/div>\n
Control<\/span>Dynamic load balancing<\/strong>Charging power follows solar production and grid load.<\/span><\/div>\n<\/div>\n

When does it pay off?<\/h2>\n
\n
\n
01<\/div>\n
\n

Sites with an existing PV installation<\/h3>\n

The added value lies mainly in adding the battery.<\/p>\n

Key takeaway:<\/strong> payback of 5 to 8 years.<\/div>\n<\/div>\n<\/div>\n
\n
02<\/div>\n
\n

Fleets that mainly charge at night<\/h3>\n

The battery shifts daytime production to the evening hours.<\/p>\n<\/div>\n<\/div>\n

\n
03<\/div>\n
\n

Sites with a capacity tariff and high peaks<\/h3>\n

Peak shaving with the battery significantly lowers annual grid costs. How that works is covered in capacity tariff and smart charging<\/a>.<\/p>\n<\/div>\n<\/div>\n

\n
04<\/div>\n
\n

Companies with a dynamic energy contract<\/h3>\n

Charging during negative hourly prices, discharging the battery at peak prices.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Does the combination pay off on your site?<\/strong>We combine your grid connection, PV production and charging profile in one calculation model.<\/span><\/div>\n

When does it not pay off?<\/h2>\n
\n
No solar panels<\/span>Battery too expensive<\/strong>Without a free energy source, the investment is too high.<\/span><\/div>\n
Mainly daytime charging<\/span>Battery unnecessary<\/strong>Solar power goes straight to the car, not through the battery.<\/span><\/div>\n
Fewer than 5 EVs<\/span>No economies of scale<\/strong>Payback exceeds 10 years.<\/span><\/div>\n<\/div>\n

Calculate it on your own profile<\/h2>\n
\n

An installer who sells you this combination without knowing your consumption profile is selling you a gamble.<\/p>\n<\/div>\n

Certipower calculates it based on your actual consumption profile. If grid capacity on your site is the bottleneck, also read what to do when grid capacity is too limited<\/a> and load balancing: what and why?<\/a><\/p>\n

\n
Install<\/strong>At the employee\u2019s home, on the company site and on the road.<\/span><\/div>\n
Measure<\/strong>Production, consumption and charging power per location, without estimates.<\/span><\/div>\n
My.Certipower<\/strong>Consumption and costs per user and per location, without Excel.<\/span><\/div>\n
Split billing<\/strong>Your employee pays nothing upfront and submits no receipts. How split billing works<\/a><\/span><\/div>\n<\/div>\n

Solar panels, chargers and a battery: profitable for you?<\/p>\n
