Naps Solar

What Naps Solar does

Naps Solar is a privately held solar energy solutions provider headquartered in Tänassilma, Estonia, with a secondary operating entity in Finland. The company designs, supplies, and installs solar photovoltaic (PV) power plants and battery storage systems for three core customer segments: residential homeowners, businesses/commercial customers (including logistics, manufacturing, retail, and food service), and housing associations (korteriühistud). Project sizes range from small residential systems of approximately 5 kWp to large commercial installations of up to 893 kWp (such as the KWH Freeze Vantaa facility). The company has roots dating to 1981 through Neste Advanced Power Systems (NAPS) and claims over 40 years of solar energy experience, with operations spanning 160+ countries through partner networks.

The company's technical stack centers on standard solar PV components — solar panels, inverters, power optimizers (for panel-level optimization and partial-shade performance), and multi-brand battery storage systems (Deye, Sungrow, BYD, Huawei, Solax, Dyness, Axitec, GoodWe, Thunor). Remote monitoring and maintenance services are delivered through a core partnership with VSV-Energia Oy. A savings calculator on the company's website enables self-service ROI estimation, while quote requests route through direct sales for both residential and enterprise customers.

Naps Solar's revenue model combines one-time hardware sales and turnkey installation with recurring maintenance contracts. Pricing is quote-based and not publicly disclosed. The go-to-market relies on a direct sales team in Estonia (phone, email, website forms), enterprise field sales for large commercial projects, partner-mediated delivery in Finland (VSV-Energia, Enerz Oy), and a global partner network for international reach. The company supports customers in accessing government subsidies (Kredex, EAS) and offers installment financing, reflecting the relatively high upfront cost of solar installations for end customers. Notable enterprise customers include Hesburger, KWH Freeze, and Kivikylän Kotipalvaamo, with KWH Freeze returning for a second project after the first.
