Poncho solar The presentation will detail the results of a year-long case study on the post-NEM residential self-supply non-export to the grid market in Hawaii. For NEM programs, the amount of cost savings and return on investment is determined by generating the maximum amount of solar PV energy possible and selling back to the grid. The key to the fastest return on investment in the post-NEM world is through achieving a monthly utility bill with Grid-Buy as close to zero as possible. To eliminate Grid-Buy needs on water heating, we customized the hot water tank into a thermal storage for Battery Optimized Discharge Hot Thermal Storage. Our system monitoring software allows for optimization of energy usage by major household appliances to reduce Grid-Buy, with dynamic battery charging and discharging to maximize savings based on TOU rates. The results from this study resulted in improvements to both the software and hardware of our hybrid inverter system. About J. Technologies: J.

It only takes a minute to sign up. I'm not looking for a recommendation for a particular piece of kit, because such a recommendation could quickly go out of date, and then the answers would be of no use to anyone else. So I'm asking, what should be monitored, to track a typical home PV system's performance and health: roof-mounted PV peak capacity is 4 kW, and there's an inverter in the loft attic connecting it to the home power supply and to the grid. Photovoltaic system's performance parameters belong to two categories: energy generation electricity units like Volts, Amperes, Watts and Watthours and supplemental some other units. Although you don't mention it, to make the answer complete, I add energy storage category if you had a battery storage attached. For a 4kW array, the actual power output you see is likely to be around 3kW if your system is operating properly, assuming the array isn't too old. For more, read on First of all, many home solar installations now are done by companies that specialize in putting together packages of the solar panels, the inverter, and a control panel to monitor the system. If you're in that situation, then you basically get what the company who wrote the control panel's software decides to give you. It's unlikely that building your own monitoring circuitry or software would be a good use of time, although if you're a DIY type, I might suggest looking at LabView or OpenEnergyMonitor to create your own monitoring system. It's also unlikely that the software features that come with your system are going to be or should be a primary factor in picking the system. I personally would rank the kind of panels, the inverter hardware, the experience of the installers, the price, and specific tax incentives as more important than the amount and kind of data you can see on the control panel, or web interface that the system supports. In terms of what you should watch, I think solar panels are a bit like a car. If you only want to watch one thing to assess a car engine's health, watch your fuel consumption e. With solar panels, kWh produced per month is probably the equivalent metric. Some systems allow you to see the production per modulewhich can help identify one bad module in your array. Having electronics on each module helps both with fine-grained monitoring, but also allows micro-inverters or DC-DC converters to tune each's module's performance independently. Another metric that may be available to you is panel temperature. Excessive temperature can be a sign of problems, and high temperatures can damage photovoltaics, like many electronics. You may also be able to see the panel output voltageor the frequency Hz of the power your inverter is producing. Familiarize yourself with the normal values for your system, and note any deviations from that baseline. Finally, your system may have a separate status output that indicates that a particular module's health is Ok, Failed, Degraded, or Unknown. Keep in mind that the solar panels can only convert energy from what the sun gives them. If you open up the PDF file for a given month there's a couple month delay in the published datafind a city near you, and look at the far right column to see total hours of sunshine:.

If you open up the PDF file for a given month there's a couple month delay in the published datafind a city near you, and look at the far right column to see total hours of sunshine:. So, in that case, you'd expect your monthly output to be higher than most years. This is a rough way to assess performance, but it's better than simply comparing to the same month last year, without adjusting for sunshine. Some off-the-shelf software monitoring systems do interface with weather and climate data services, and show some measure of sunshine. The ones I've seen show instantaneous solar irradiancewhich I don't think is as useful as longer term sunshine data. It's important to know what to expect from a solar PV system. Panel performance will degrade slowly, and smoothly, over time, so that's to be anticipated. Inverter problems may show up more abruptly, and before the photovoltaics reach their end of life. Of course, physical damage to your panels can instantly affect their performance, too. If you haven't already had your system installed, or have a maintenance visit coming up, ask this question of your installerwho will likely have important experience with the specific failure modes of your hardware. As there are already two excellent answers I would just like to add what I found useful to monitor:. As Nate's answer suggests the energy produced per month is a good metric for keeping track of the PV systems status supplemented by information provided by the inverter. And as the amount of energy is depending on multiple parameters and could not just be compared to the initial values of the system the comparison with other PV systems seems to be the most easy way. So if output data is made available by other PV owners and operators of the respective region this is a very simple yet pretty accurate estimate.

Poncho solar William Walker and his wife, Mi Chong, wanted to join what's seen as a solar revolution in Hawaii. Their plans shifted the day after the PV panels went up in early October. The Walkers learned from a neighbor about a major change in the local utility's solar policy. It led to those 18 panels sitting dormant nearly three months later. Hawaiian Electric Co. On many circuits, the utility said, there's so much solar energy that it poses a threat to the system and a safety issue. Studies are needed on whether grid upgrades are necessary. If they are, residents adding solar must foot the bill. And starting immediately, contractors and residents would need permission to connect most small rooftop systems to the grid. The new HECO policy was included deep in the text of emails the Walkers' solar contractor had sent, but it escaped their notice before installation. There's really not a lot of substantiation. My belief is it's purely profit-motivated, to keep people away from PV and keep them on the grid. The policy change halted what has been a solar surge in Hawaii. Installations there jumped percent last year from More than 4 percent of households have photovoltaics. Hawaii last year led the nation in the portion of its electricity that comes from solar, with 2. The Aloha State burns oil to make electricity, and prices for the fuel have jumped in recent years, igniting demand for alternatives. The state's tax credit for solar energy made it additionally appealing ClimateWireMay 6. The new struggle on Hawaii foreshadows what the rest of the country could face as solar moves closer to the mainstream, several involved in the debate said. That is happening in real time in Hawaii. That policy -- which exists in some form in 43 states and the District of Columbia -- lets households with renewable energy earn bill credits for surplus power delivered to the grid. Utilities in states with growing levels of solar have argued that fixed fees and other changes are needed because customers with net metering bill credits don't pay their fair share of transmission and distribution charges. The new program will need to be "based on electrical system costs and benefits to nonparticipating ratepayers. Arizona's utility regulator last month approved a hike in the surcharge that solar customers with net metering pay the state's largest utility. Charles Wang, with the Hawaii ECO Project, at a solar conference in San Diego earlier this month warned people from other states that Hawaii is a "cautionary tale" and "something that you will face down the road in your marketplaces. If you push it to the corner of the room, it's going to fight back. That's what's happening right now. It's more controversial on Oahu, however, because it's home to about 80 percent of the state's population. Aboutpeople live on Oahu. On Oahu, 10 percent of utility customers will have rooftop solar by year-end, Rosegg said. Solar Poncho Song 1 Hour
