The Department of Public Utilities is looking at changes to standards for interconnection of customer-owned rooftop photovoltaic systems. Photo courtesy LAC COUNTY NEWS RELEASE The Los Alamos Department of Public Utilities (DPU) is proposing changes to Rule E-5 under its rules and regulations. Rule E-5 covers standards for interconnection of customer-owned rooftop photovoltaic (PV) systems. The first rooftop PV system that was interconnected to DPU’s electric distribution system was installed in 2003. Ten years later, there were 32 PV interconnections. By the end of 2023, there were 471. This growing…

Abstract Traditionally, isolated and non-isolated boost converters are used for solar photovoltaic systems (SPV). These converters have limitations such as low voltage gain, less voltage ripples, temperature dependence, high voltage stress across the switches, and being bulky in size. Besides, the solar PV system also has non-linear characteristics between I–V and P–V, and the energy yield potential is affected by partial shading phenomena. Therefore, maximum power point tracking (MPPT) is being added to the SPV system to get the maximum output power under steady and dynamic climate conditions. Although the…

Yes. A 6 kW solar power system can save you around $1,200 per year on a property with favorable sunshine conditions. With an average cost of $2.97 per watt, a 6 kW system would cost around $17,820, or $12,474 after the 30% federal tax credit. Based on those figures and annual energy savings, you could achieve a payback period of about 9.01 years. The best solar panels have a 25-year warranty, more than double the average payback period in Kansas City. Solar is also worth it if you are looking…
