Solar PV for Internet resilience (Part 1): Designing your system

By · Published by Everything Blog

In short

Planners must carefully evaluate their total electrical demands by cataloging network hardware, cooling equipment, and secondary draws before building out solar systems. Measuring energy needs through power meters, equipment labels, or digital tools ensures that the chosen setup meets minimum peak power capacity. Designers must also choose between independent off-grid deployments and grid-connected models with islanding capabilities. While grid-tied configurations involve complex management across multiple paths, they allow facilities to sell back excess power to offset operational expenses.

As the Internet reaches more remote locations and carries an increasing share of everyday mission-critical services, from telephony and messaging to banking and telemedicine, reliable power supply is essential for both end users and network infrastructure operators.

Solar photovoltaics (PV) with battery energy storage has become an attractive alternative to long, precarious grid supply lines and diesel generators, particularly over the last decade. Solar panel prices have plummeted to a fraction of what they were, and with reliable high-capacity lithium iron phosphate batteries also becoming available in quantity at lower prices, solar PV is now generally a worthwhile addition to residential and commercial grid supply, even in urban areas.

For the newbie, however, solar PV can still be bewilderingly complex. This can lead to projects that fail to meet local needs, stall, or are abandoned early, with infrastructure ultimately removed and never replaced. I have seen this happen even in projects run by power utilities in developed urban areas, so if you are in a remote area and you are feeling a little anxious, that’s understandable. But it can be…
