01About the client

PT Aruna Cahaya Pratama (Aruna) is a solar energy solutions provider for the industrial and commercial sectors, based in Jakarta. Its work covers permitting, design, procurement, construction, and operation and maintenance, with two forms of installation: ground mounting on open land and rooftop mounting on building roofs. Aruna offers several cooperation models, including a scheme with no upfront capital expenditure, and has completed projects for companies such as Astra Honda Motor, Indomaret, BCA, and Bogasari.

02Challenge

Buyers of industrial-scale solar power do not decide in one visit. What is assessed is not the product but the calculation: what capacity fits, how long the payback is, and who bears maintenance while the system operates. There is also more than one cooperation scheme, and the scheme with no upfront capital expenditure is the hardest to explain in one sentence. On the other hand, proof of work is scattered across many locations with differing capacities, so an ordinary project list shows nothing about the track record.

03Legia's approach

Each project gets its own page, complete with installed capacity, type of installation, location, year, and impact figures such as annual electricity production and emissions savings. The page also carries environmental, social, and governance impact separately, because this is the part clients reuse in their own sustainability reports. The spread of projects is shown as a map with points that can be clicked by region, so the track record reads as reach, not as a list. The cooperation models are split from the solutions page so readers who come for financing do not have to go through the technical explanation first.
