Im have received two quotes for a 10kw system and they are roughly around the same price so Id love some comments about either of them: 1. I saw in a youtube video that a faulty panel can be identified by taking a voltage reading from Earth to + then Earth to and comparing the values, the difference will (and in which direction, either + or -) determines the suspect panel counting from the total voltage down the Voc of each panel by what the difference is. One question, with the Maxim chips, do you get the same sort of panel-level monitoring and fault detection as with optimisers or micros? At the end of the day, whether you choose SolarEdge vs Enphase should come as a direct result of an in-depth analysis of your project and energy needs. Ill give my figures for 72-cell panels: 10. When it comes to warranties, you can see that both SolarEdge and Enphase offer similar packages. inverter operating V. Then you have the situation where the shading in a section is insufficient to operate that sections BD. The IQ8 is coming out over the next few quarters, and will have embedded microgrid capability, that is, without storage, you will still be able to form a microgrid if the utility grid fails. THIS IS MORE SERIOUS AS THE I REDUCTION IS PROPORTIONAL TO THE SHADED AREA OF EVEN JUST ONE CELL IN AN UN-BYPASSED SECTION. After the installation they have always been willing to answer questions we have. On the house I live in I chose to install microinverters. my PVs have Enphase microinverters which are monitored by Enphase Enlighten web-based system (using Enphases Envoy-S sitting behind my meter box).

This type of solution provides for more flexibility but a significantly lower efficiency rating. We cannot argue that there is a reason why these two companies hold almost equal amounts of the market share. The system comprises 20 Alpha Rec370 panels, 6Kw Solar Edge Inverter with Optimisers for each panel and of course, the Tesla kit. Net energy metering (NEM) is a billing arrangement in which excess electricity production from photovoltaic (PV) solar panels is tracked by your electricity provider and subtracted from your monthly electric utility bill. The entire project took a bit longer than expected. From Christopher, the install team, to the post install communication has made the experience seamless and enjoyable. facing true north at 359 deg. Paul K They manufacture batteries, inverters, among other solar-related accessories. SolarEdges real uniqueness comes from its offering of a full suite of products. As a string of panels is a string of three times as many 1/3 panels in series, a good bypass diode avoids any current restriction, with the only consequence of a dead 1/3 panel being reduction of the string voltage by 1/3 of a panel plus 1v diode drop. Thats the trouble with kids these days. So far the peak DC wattage weve seen on the replacement inverter is 2.1kW whereas the previous unit we think was reaching higher but the peak was never recorded so are going by memory (there was previously no issue with the solar so it was not checked, monitored & we have no graphs or historic data lesson learnt, Im exploring PVOutput).

You can accumulate credit with surplus generation during the sunny summer months, and use it during winter when solar generation decreases. While you may find competing information regarding different brands, before deciding which you should choose, you first need to understand the 3 different types of inverters: Microinverters and power optimizers are often collectively referred to as Module-Level Power Electronics (MLPEs). Maybe Im wrong and MTTP arent that smart and just look near Voc. SunPower earns its position as the top national installer on our list for a handful of reasons: It installs the most efficient solar technology on the residential market, offers the most expansive service area and backs its installations with a warranty well above the industry standard. Materials Warranty Term. Back in 2015 I put together this infographic to help you decide (and this blog post too). We highly recommend Lumina Solar! We recorded about a 15% kWh production difference (reduction) between what the estimator calculated & our solar systems performance today. The inverter presents a load to the array. Customers benefit the most by knowing that they can have data from monitoring each panel so they can reduce the impact of shading and other performance issues. mustafa They went above and beyond to help an old fart like me understand the solar process, and they earned a lifetime client in me. So our beloved power company refused to allow me to install a 3 phase 27.6Kw Solaredge inverter (needed for both EV and some high amperage 3 phase gear here) because the DC voltage is more than their recommended maximum on the roof. Your utility company will pay you for this power production through credits that can be applied to your monthly energy bills. If a BD was damaged, it is possible to replace it (if you can find it an economical manner), but if the PV cells within its bound are also damaged then the panel would need replacing. LG batteries have proven themselves as one of, if not the, best solution on the market. I knew right away that they were the company I wanted to work with. | 10/28/2022. I suspect the 2nd string different ~200W W reduction would account for the 15% kWh production loss though. The excess energy produced by your solar panels is measured by your homes electricity meter. Many neighbors have installed solar panels and shared their concerns and regrets with me, and I took this information to be a better consumer. We communicate with you using only your preferred method phone, email or visit, and we never use pushy sales tactics to pressurize you into making a decision.

No one can provide an honest, objective, generalized ranking between the two, as they offer completely different technologies and capabilities. If youve ever had early morning frost on the roof, the panel has been at 0C, or lower in the case of many parts of Australia. My system was installed 3 months ago, made operational by Peco 2 months ago, and I received a communication today from Peter to check on how the system was working. The existing 6 year old solar array configuration is configured as follows: They have been installed for over a year now and it has been a pleasure to work with them throughout the process. Their latest products, while robust and comparable in theory, do not always function as intended. This drop in current affects the current in every other panel in the series string. The Enphase Ensemble costs far more than some of the industrys best solutions while much less power output and storage capabilities. The biggest advantage of a DC optimiser that is independent of the string inverter like Tigo is you dont have to put them on every solar panel. Sad in Rolling Hills Estates! My wife and I had a great experience working with Lumina Solar through the whole project life cycle. If net metering is available in your area, you will be credited for your surplus energy in one of two ways: Note: This is just a simplified example the exact kWh retail price and solar feed-in tariff will depend on your electricity plan.

Not 250w as written above. If that werent enough, SunPower systems come packaged with products all manufactured in-house by its sister company, Maxeon. This will reduce the panel voltage somewhat (say 10V under load) so an affected string will have a slightly lower power generation (due to a lower series-string V) than an unaffected string (assuming both are currently unshaded). (Even if you decide to put optimizers on the second system it will be cheaper than retrofitting them onto an existing system.). When we realized it was finally time to replace our roof, we were ready. Hi, The issue for home- and business owners? AC-coupled batteries still store electricity as DC, they just have a mini-inverter built in which allows them to receive AC, convert to DC, store, convert back to AC and push to the home.No one has a definitive answer as to which solution works best, as it will mostly depend on your circumstances, but this is one of the areas in which SolarEdge and Enphase differ the greatest. When your solar system produces more kilowatt-hours of electricity than your home is consuming, the excess generation is fed back into the grid. I am fixated on understanding why this condition ocurrs.So, Ill keep digging. | West Hills, California The company, with headquarters in Israel, was also founded in 2006 and offers a wide range of inverters for residential and commercial use. When managed correctly, net metering is beneficial for electricity consumers and power companies. I couldnt see a review for the specific model but maybe I was having a mans look. Residential Solar. Also, Im not a PV Tech, but Id suggest that it would be better if the 2 7-panel strings were kept separate all the way back to the inverter, feeding into 2 separate MPPT channels. In the argument of SolarEdge vs Enphase as it pertains to scalability, you can easily see a clear winner. When all the approvals were received, it took a few days to get instructions on the final step"Flip the switch". i put a clamp on both Dc lines and noticed the current going up and then suddenly going down during the daytime near solar noon.

One uses SolarEdge with optimizers, at $2.50 per watt, and another uses Enphase IQ7 microinverters, at $2.80 per watt. I absolutely cannot recommend them enough. A smart panel with DC optimiser pre-installed at the factory. Lumina was head and shoulders above them. When each string was individually checked we got very similar voltage readings (Voc) & also when connected to the inverted (via the DC distributor fuse box on the roof popped out one fuse at a time). System was installed Sept. 2022. | 11/07/2022. Im fairly sure that the inclusion of the DC optimisers are partly responsible for maximising the production in the system the only way to determine for sure would be to put an identical system without the optimisers and measure the differences. The quote and planning process went well and they were knowledgable about the questions we had. But microniverter systems are even safer by design (no high DC voltage), and DC optimisers and microinverters both shut down the solar panels fully in fault conditions increasing their safety. The price is calculated based on how many units you order: a single Powerwall sells for $10,500, but two units will cost $17,000 ($8,500 each). (OK, the diode would drop around 0.6 to 0.7v at low current, but at full string current you'll see around a volt.) No other site has covered renewables as long as us, which means we have more data and insider information than other sites. We have notified them of these many times.

We are delighted with our solar production so far and excited to contribute to renewable energy solutions while saving money. | Dover, Pennsylvania In a Maxim panel these 3 microchips replace the bypass diodes. | 11/07/2022. This happens through the creation of hot spots where shaded cells result in energy being dissipated as heat. | San Francisco, California String current will probably be reduced somewhat. The system was not even 6 months old and now 19 of the 27 micro inverters are not working. DATASHEET HD-WAVE. Over the Year, the power production from the two different units is only about 250kw (each) less than what the other 5 units produce in that row. Here is a brief explanation of how it happens: https://www.pveducation.org/pvcdrom/modules-and-arrays/hot-spot-heating. What have you chosen and why? We also had lots of technical questions as we did our own research and Molly was always able to answer them. Finally, Enphase inverters come with a full 25-year warranty. Micro-inverters are a totally different approach to PLO. Modern power meters can measure electricity flow in both directions, so they tick up when you pull from the grid at night and count down when your solar panels are producing an excess amount of electricity. He was always quick to reply with answers to our questions and if he didn't have the answer right away, he responded to let us know he was looking into it.

Why is the Amps ramping up beyond 15A (seen 16A) on the inverters display? around 9am each day, two of the optimisers report a voltage of 60v. Scalability matters to clients who project an increase in their future power demand in case of adding an electric vehicle, or add a large battery backup system for example. To make matters worse, the electrical contractor hired to do our job was extremely flaky. This type of solution provides for more flexibility but a significantly lower efficiency rating.
