Wiwaswan Wisesa Pamudji

Founder & Director

Esa founded LEIN Power to make going solar easy, affordable and within reach for every Indonesian family.

He has spent his career where money, buildings and customers meet: analysing investments, developing townships, high-rises, hotels and industrial estates across Greater Jakarta and Surabaya, and leading sales planning for international brands. Those years shape how LEIN works today: clear numbers, careful engineering and a team that listens first.

Esa holds a bachelor’s degree in Finance from Prasetiya Mulya Business School.

Product brands we use.

LEIN Power partners with the manufacturers’ official representatives and authorised distributors for every component of a solar power system — modules, inverters, batteries, cables and connectors, protection and switchgear, mounting and monitoring — so that availability, product authenticity and manufacturer warranty service are assured. Energy simulations are run with industry-standard software. As our primary option we propose modules, inverters and batteries from Tier 1 manufacturers — listed in the BloombergNEF (BNEF) Tier 1 List and/or S&P Global’s Tier 1 Cleantech Companies list, the bankability benchmarks used by financiers. As a more economical alternative, we can also offer, on request, other brands that have passed our technical qualification, still with the manufacturer’s warranty and LEIN’s after-sales support.

Tier 1 — ¹ listed in the BloombergNEF Tier 1 List (PV modules, Q3 2026 edition; energy storage, Q2 2026 edition) · ² listed in S&P Global Tier 1 Cleantech Companies (2026). Tier 1 status reflects market acceptance and bankability, not a quality guarantee; it is reviewed with every new list release, and every product still passes LEIN’s technical qualification. Product specifications and warranties follow the manufacturers’ official documents.
