Sigenergy tells us PPL Electric Utilities has approved its system for interconnection. That gives PPL customers another battery option, including one that can pair with V2X EV backup for non-Tesla vehicles.

Tesla has expanded Powershare Home Backup to Model 3 and Model Y. Paired with a Powerwall 3, the car can keep a typical home running for about two days. Here's what qualifies, what it can't do, and the option for non-Tesla EVs.

TOPCon has replaced PERC as the dominant solar-cell technology, giving homeowners more power per square foot and modest improvements in heat performance and long-term output.

Pennsylvania crossed 2 GW of installed solar in July 2025 and has continued growing. Here is what the state's latest policies—and today's PECO rules—actually mean for homeowners.

What installer bankruptcies mean for equipment warranties, monitoring, financing, and repairs—and the steps Southeastern Pennsylvania homeowners should take.

Saturday's microburst slammed Lower Merion, Narberth, and West Philadelphia with 70 mph winds, leaving thousands without power for days. Our solar+battery customers never lost a light.

PECO rates are up over 20% from last year, and summer AC season hasn't even started. Here's how Philadelphia-area homeowners with solar panels keep their bills under control — and what you're paying without them.

Battery storage is everywhere in solar marketing right now. But does every solar homeowner in southeastern PA actually need one? Here's our honest take.

PECO has filed for a 12.5% electricity rate increase starting January 2027 — about $20 more per month for a typical household. Governor Shapiro called it 'pure greed.' Here's what you need to know.

Spring in the Philly region means longer sunny days and the start of severe weather season. Rising PECO rates, a strained grid, better battery tech, and a narrowing incentive window all point the same direction.

Your electric vehicle's battery is 5-7x larger than a home Powerwall. With bidirectional charging (V2X), it can power your Southeastern PA home for days during a grid outage. Here's how it works.

House Bill 501 could require 35% renewable energy in PA by 2035 — potentially increasing SREC values and strengthening the economic case for solar across Southeastern Pennsylvania.

PECO's TOU pricing charges more during peak hours (2-6 PM) — exactly when your solar panels produce the most. Here's how SE PA solar owners can use this program to maximize savings.

With shifting incentives and rising PECO rates, many SE PA homeowners wonder if they missed the boat. The reality: the financial math for solar in 2026 is more compelling than ever.

Despite not being the sunniest state, Pennsylvania's solar economics are compelling. 4-5 peak sun hours per day, falling panel costs, SRECs, and 1:1 net metering make solar a strong investment.

With 50 gigawatts of new solar installed nationally in 2024 and strong PA incentives, Southeastern Pennsylvania is positioned as one of the best solar markets in the Mid-Atlantic region.

Demand charges can represent 30-70% of a commercial electric bill. Solar + battery peak shaving can dramatically reduce these charges and protect against costly business downtime during outages.

Understanding your solar payback period is simple: subtract incentives from total cost, then divide by annual savings. For most SE PA homeowners, that's 8-10 years with 15-20+ years of pure savings after.

The Tesla Powerwall 3 stores 13.5 kWh and provides seamless whole-home backup during grid outages. Pennstar Solar is a certified Tesla Powerwall installer serving all of SE Pennsylvania.

Pennsylvania's 1:1 net metering means PECO credits you at the full retail rate for every kWh your solar panels export. It's essentially a free battery — and it makes solar far more valuable here than in many other states.
