Selling solar surplus requires no battery purchase, while storage can increase self-consumption and offer more control. Compare both over the same period using realistic tariffs, efficiency, warranty and installation cost.
A sensible first check
No sales pressure and no guarantee: start with an indication and have the final design and quotation checked by a qualified professional.

Exporting electricity uses the existing grid connection and contract. The result depends on compensation and charges but avoids a separate storage investment.
A battery can move part of the daytime surplus to later hours. Not every exported kWh can or should be stored because capacity, power, efficiency and seasonal patterns limit use.
Compare a cautious, central and favourable scenario. Include replacement risk and do not assume today's hourly price differences remain unchanged for the full lifetime.
Frequently asked questions
Neither. The answer depends on the household profile, battery quotation and energy contract.
Yes. Most battery households still export some electricity and buy from the grid at other times.
No. Also consider warranty, usable capacity, safety, flexibility, comfort and financial uncertainty.
