Frequently asked questions
Do solar panels work in Finland?
Yes. Panels generate electricity in cool and cloudy conditions, with most annual production from spring through autumn.
How long is the warranty?
Warranty depends on the product and manufacturer. Product-specific terms are shown on each product page. A voluntary manufacturer warranty does not limit the consumer’s statutory rights in the event of a defect.
Can I add a battery later?
Yes, provided the inverter and system design support a later battery upgrade.
How are online payments processed?
Online payments are processed securely through Stripe. PowerNest does not store full payment-card details in its own systems.
