INVERTERS

1. String inverters: Save some money if your roof is simple

Solar companies have used string inverter technology for decades. It’s an incredibly reliable, tried-and-true technology and is the most affordable option available today. String inverters work best for those with relatively simple roofs that get lots of direct sunlight

Centralized DC to AC conversion

Easier system maintenance with no electronics on the roof

Most affordable option

Only offer string-level monitoring

How it works

In a string inverter setup, an installer will arrange your solar panels into groups connected by wires referred to as a “string”. Multiple strings of panels will then be connected to a single inverter, which is called a centralized inverter. This transforms the DC electricity produced by the panels into usable AC electricity for your home or business.

The main downside of a string inverter is that every panel connected to a string is limited to the output of the weakest panel. Modern solar inverter and panel technology allows individual panels to continue producing power even if a part of the panel is shaded, but without module-level power electronics, string inverters can only optimize power output at the string level, not at the individual panel level. 

String inverter systems aren’t the best solution for homes prone to shading throughout the day, as linked panels are limited to the output of the weakest panel (whether due to being partly in the shade or any performance issues). However, their ease of installation and lower prices make them attractive to homeowners and installers.

2. Microinverters: Great if you may want to increase your system size in the future

Microinverters utilize module-level power electronics (MLPE) and are by far the most popular type of inverter on the Marketplace, even though they’re also usually the most expensive. 

Panel-level DC to AC conversion and optimization

The power output of each panel is optimized independently

System size can be expanded easily in the future

Electronics are all located on the roof

How it works

Unlike string inverters, which convert DC power into AC power for a group of connected panels, microinverters are connected to each individual panel.

Installers usually mount the microinverters onto the back of the solar panel, but they can also be placed next to the panel on your solar racking system.

As a result, microinverters allow you to monitor the performance of individual solar panels.

3. Optimized string inverters: Can help you get the most out of your system

Power optimizer systems offer many of the same benefits as microinverters and are often a compromise between microinverters and standard string inverters.

Centralized DC to AC conversion + panel-level optimization

The power output of each panel is optimized independently. Total output isn’t limited by lower-performing panels. 

Provide both system and panel-level monitoring

Future system size increases may require an additional central inverter

How it works

Like microinverters, systems with power optimizers have MLPE components. They reduce the impact of shading on panel and system performance, as well as offer panel-level performance monitoring.

Optimized string inverters are able to manage power generation on a panel-by-panel basis, similar to microinverters, but they then send the power to a string inverter to convert the DC power into AC power collectively. 

While optimized string inverters optimize panel output independently, they still convert electricity centrally. Instead of converting the DC electricity to AC electricity at the panel site, they “condition” the DC electricity and send it to a string inverter for conversion.

If your roof experiences shade during the day, the panel-level optimization afforded by power optimizers often results in higher system efficiency – and a better long-term return on your investment – than using a string inverter alone.

Choosing the right solar inverter for your system

Ultimately, you want to pick an inverter that enables your solar panel system to perform well without breaking the bank. Talking to your installer about the inverters they offer and what they think will be the best fit for your system is the perfect place to start.

It’s important to remember that microinverters and optimizers aren’t the only available options. String inverters are the way to go if you’re looking for the most wallet-friendly option and have a south-facing roof with little shade. But if your roof is more complicated, microinverters or power optimizers could significantly increase your savings with solar down the line.

SOLAR AMC (ANNUAL MAINTENANCE CONTRACT):

MAINTENANCE IMPACTS YOUR BOTTOMLINE

Every Solar PV installation is a long term investment, deemed to give you returns year after year. But like any other investment, you need to ensure these returns are optimum and your assets value is safe.

A Solar PV installation that has not been cleaned for over a month will give you a power yield less than it’s rated capacity. The power generation can fall by as much as 30%.

Then there are risks of outages and downtime on account of component failure, electrical faults etc. These are just a few of events that can directly effect your bottom line.

THE ANSWER IS PREVENTIVE, PREDICTIVE AND CORRECTIVE MAINTENANCE OF YOUR SOLAR PV INSTALLATION.

WE PROVIDE COMPREHENSIVE MAINTENANCE

WE BRING YOU THE EXPERTISE, TECHNOLOGY, AND WELL-DEFINED PROCESSES TO ENSURE COMPLIANCE AND TO MAXIMISE THE PERFORMANCE OF YOUR SOLAR ASSETS.

OUR O&M SYSTEMS EMPOWER YOU TO MONITOR AND CONTROL THE COST OF RISK MANAGEMENT.

PRO-ACTIVE MAINTENANCE

Our exhaustive maintenance service packages account for the specific needs of every solar plant owner, solar project developer, and investor.

OPERATIONAL INSIGHTS

As your solar plant operations and maintenance partner, we also provide technical insights about your power plant and their effects on your financial returns.

WARRANTY ASSISTANCE

Our services also include long-term maintenance planning with equipment manufacturers or contractors and assistance in warranty claims.

Why Solar AMC is a Must for Commercial and Industrial Solar Plants?

Commercial & Industrial solar (source: https://dasenergie.com/solution/solar-amc/)

It may become very difficult for you manually check the entire solar system weekly or even monthly to find the issues. For example, a 200 kW C&I solar plant can have 400+ solar panels, a highly complex electric circuit connecting every component.

Any unnoticed faults, short circuits, or damages can reduce the plant’s overall production. Just imagine how troublesome or financial loss it will become if your commercial solar plant stops suddenly. Your factory or business activities may become in operational that day. To avoid these unnecessary circumstances, you need professional C&I solar maintenance services. Regular checkups will reduce the chances of short circuits, fire incidents, etc.
