Solar monitoring platforms collect production data from the equipment on a roof or plant, then show yield, faults and energy flows in a portal or app.
This guide ranks fourteen products on which equipment they accept, what a monitoring tier costs, whether portfolio and API features exist, and how data and sign-in behave when a vendor changes platforms.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
In short
What solar monitoring platforms do
Solar monitoring platforms pull generation and equipment readings from inverters, optimisers and meters, and present yield, faults and energy flows to owners and installers through portals, apps and APIs.
Our order comes from five tests, taken in turn: effort to set up, what you really pay, what happens to your data on the way out, how locked in you are, and the intended customer. A challenger rule applies on top. Places 1 to 3 are kept for lesser-known vendors when the category has them; large brands rank from 4. We explain on how we work why the tests are these five and why no product receives a score.
Module-level monitoring with a published free tier and annual per-site pricing
Ranked #1 of 14 in Best Solar Monitoring Platforms in 2026.
Free tierPublished pricingElsewhere
Energy Intelligence is sold in three steps. Basic lists system health, power flow, module-level power and monthly reports. Premium covers sites up to 35 modules and adds minute-level data, full playback and an API, then charges per extra module.
Professional adds a multi-site view, commissioning tracking and support tickets raised from the platform. The page cites more than 20,000 supported equipment types, among them third-party inverters, meters and batteries, but the text we read gives no list.

Cloud and app layer for Huawei inverters, storage and plant management
Ranked #14 of 14 in Best Solar Monitoring Platforms in 2026.
Pricing on requestElsewhere
The pages we read describe product families more than software behaviour. SUN2000 Smart PV controllers, LUNA2000 storage and SmartGuard are listed beside the app and SmartPVMS, but no page itemises monitoring functions, alerts or reports.
That makes this entry the thinnest in the list, and it sits last for that reason. A buyer should ask for a demo and for written statements on hosting and certification before treating FusionSolar as comparable with the better documented portals.

Solar monitoring platforms pull generation and equipment readings from inverters, optimisers and meters, and present yield, faults and energy flows to owners and installers through portals, apps and APIs. What separates these products is rarely a feature. Work through the steps below.
01
Start with pricing transparency
Prices are public at 3 products (Tigo Energy, Fronius Solar.web, Enphase Enlighten) and on request at the remaining 11, so budget time for quotes if your favourite is in that second group.
02
Weigh the vendor's home jurisdiction
Check the vendor's home market (Elsewhere 8, Europe 4, North America 1, Asia-Pacific 1), because that is where subpoenas and data requests arrive first, whatever region holds your files.
Solar monitoring platforms that only read one inverter brand
The first split in this market is between portals built by an inverter maker and tools that read other makers' equipment. Fronius Solar.web speaks only of Fronius plants, Huawei FusionSolar names only Huawei products, and GoodWe SEMS links a device list covering GoodWe's own inverters and IoT hardware.
Tigo Energy says its platform handles over 20,000 equipment types from other makers too, and Solar-Log says it works with over 3,000 components. Those are vendor claims, not tested lists. A mixed fleet is where the choice bites: an owner who later adds a second inverter brand may need a second portal. Ask each vendor for the device list, in writing, before signing.
Request the supported-device list for every inverter, meter and battery you own
Ask what happens to history if you add a second brand later
Test one real device in a demo account before committing
What a free tier of solar monitoring leaves out
Several portals call themselves free, and the gaps sit in the detail. Tigo Energy's Basic tier stays free as long as the hardware is monitored, with 15-minute readings and limited playback, while Premium moves to minute-level data with full history and an API. Fronius pairs a free Solar.web tool with a premium version, yet lists no prices or duration.
GoodWe calls SEMS cost-free without pricing SEMS+, and the Fimer Aurora Vision FAQ mentions services free of charge without naming them. Enphase publishes API plans from a free Watt plan with attribution required. A free label says little about readings, history or export, so read the tier table, not the headline, before assuming it covers your site.
Compare data interval and history length on the free tier against your needs
Ask which features, such as API access, sit behind the paid version
Get the free-access duration confirmed in writing
Portfolio and maintenance tools in solar monitoring: meteocontrol and its rivals
Owners of many plants need more than a dashboard. meteocontrol links VCOM Cloud to an offline O&M app for tickets and work orders, a CMMS for service reports, Shared Assets for outside partners and mc Assetpilot for portfolio finance. Solar-Log pairs monitoring with feed-in control and direct marketing links.
SMA Sunny Portal offers grouping and portfolio management for PV professionals, and Fimer Aurora Vision names a Plant Portfolio Manager app without describing it. Tigo's Professional tier adds a multi-site view and support tickets from the platform. The hole to probe is ticketing: only some vendors describe it. None of these pages shows prices for portfolio features, so ask each vendor to show a ticket raised and closed in a demo.
List the operations tasks, such as tickets and reports, that you need in the same tool
Ask how outside contractors get access without sharing your login
Confirm which portfolio features are included in the quoted price
Data exit and platform migration in solar monitoring portals
Platforms change, and your history has to survive. SMA Sunny Portal is moving users to a new platform country by country; just two months of performance curves move across, with older data open for a short while in Sunny Portal Classic. Several older SMA gateways are left out of the move entirely. meteocontrol is shifting its VCOM sign-in to mc Cloud.
Victron VRM documents a JSON API and Enphase publishes API plans with monthly request caps, while Sunny Portal allows Energy Balance download for up to one year. Few other pages state export terms. An API that exists on paper still needs a request budget, so test an export before it matters, and put the export promise in the contract.
Ask for a full-history export format and test it on one site
Check whether an API plan has request limits that fit a full download
Find out what happens to old gateways when the vendor retires a platform
What goes wrong most often when buying solar monitoring platforms
Choosing a portal by the inverter brand alone, then finding that a second brand added later needs a separate login and history.
Treating a free label as proof of full features when the free tier may limit data interval, history length and API access.
Skipping a data export test, so a platform migration or contract end leaves years of production history unreachable.
Assuming a vendor's security or AI claims are certified when pages such as Sungrow iSolarCloud and Hoymiles S-Miles Cloud name no certification or hosting location.
