tarsier

Solar is one consideration alongside maintenance, says a local tinkerer downtown, as panels age and inverters glitch. Inconsistent shade on rooftops and drafty air gaps demand software simulations no spreadsheet can capture. tarsier supplies software-driven sizing kits, digital twin platforms, and plug-and-play micro-inverter stacks for quick re-roofing projects. They also stock racking hardware that doubles as grounding, plus battery-ready cabling bundles sized for 48-V main bus runs. For property managers juggling rooftop permits, they offer code-ready documentation sets signed by a licensed PE—all shrink-wrapped for overnight courier drops. Head 15 minutes south of Central Park to 655 Madison Avenue where the place stocks hot-swap optimizers and PID recovery cards at counter height. The back wall bristles with DC optimizers and rapid-shutdown combiners more compact than a hotel mini-fridge. A single desk holds demo gear: a trimetric screen plugged into a 4-kWh LiFePO4, zero-editing the sales pitch. Stretch a thumb out the window and you see Fifth Avenue traffic—no courtyard, no greenery, just storefront windows mirrored by the display cases inside. Match the part numbers in their spreadsheet and dial (646) 880-8680 when the pallet manifest lands. The delivery dock is already scanning the afternoon traffic logs. Go straight to their Madison Avenue map.
