Evaluate subscriptions and SGU

In this document

You will learn how the Solargis subscriptions work, what Solargis units (SGU) are and how they are spent, why subscription continuity matters, and what the limited Evaluate access means.

Solargis Evaluate subscriptions

If you want to access the Evaluate application, you must purchase a subscription. By buying a subscription, you will gain access to Evaluate, get Solargis units (SGU) that you can use to activate projects with the selected datasets, create a design of photovoltaic (PV) power plants, run simulations, and get your PV energy yield data to evaluate the project’s feasibility.

Subscription tiers

We currently offer only one subscription tier, and you can buy it by contacting our sales team.

Our subscription tier includes pricing plans that offer different amounts of SGU and discounts, with higher discounts for higher purchase value. Our sales team will provide you with more information about the price plans and will help you purchase the subscription.

Evaluate access

After purchasing the subscription, you can log in to your Solargis account and access the Evaluate application. The Evaluate access status in your account administration section will be set to Full access and you can start working on your projects.

Continuity of service

The continuity of service (Evaluate application access) directly depends on the continuity of your subscription periods. It determines the access to your projects, SGU, and paid features and is indicated by the access status in your account administration section.

The following table summarizes the key attributes of each status:

Access status	Description
Full access	You have full access to: All Evaluate features. Energy system designer. Your remaining SGU credits. You can activate projects, create designs, and run simulations (subject to your SGU balance).
Limited	You have full access to: All Evaluate features apart from simulations. Energy system designer. View your existing projects. You can not: Access and use your SGU. Activate new projects or run simulations.
Terminated	You can not use the Evaluate application or any of its features. Your access to the application is blocked. You will lose all your unspent SGU. You may lose all your previous project data.

The limited access to our application while your subscription period is pending renewal is offered by us as a gesture of goodwill. The duration of this access is 15 days and will be changed to Terminated status afterwards. We appreciate your understanding and encourage you to renew your subscription promptly.

Access status mechanism explained

Specific relations exist between Evaluate access status, paid Evaluate features, and SGU availability, which depend on the continuity of your subscription periods.

Continuous subscription renewal

Continuous subscription renewal means that a subscription remains active without any interruptions or unpaid gaps between paid periods, ensuring that the service is consistently available to you as long as you maintain your payment schedule.

There are two ways you can achieve it in our subscription model.

The subscription is paid on time/before the end of the previous subscription period.

The subscription is paid back, covering the gap between the previous subscription period's end and the date of payment, creating a continuous subscription renewal.

The key advantage of continuous subscription renewal is that your previously unspent/frozen SGU will be added back to your account. You will not lose them once you renew your subscription.

Interrupted subscription renewals with gaps or limited access periods

Interrupted renewal periods refer to a situation where a subscription experiences gaps in payment, resulting in periods during which the service is not available or limited.

The following scenarios are considered to be interrupted in terms of service payments.

The previous status of your Evaluare access was limited when your new subscription period started. This happens when the new paid period does not cover back the limited access period and begins, for example, from the date of purchase instead.

The previous status of your Evaluare access was suspended when your new subscription period started. This also happens when the new paid period does not cover back the gap and begins from the date of purchase instead, or the limited period was too long, and the account has been suspended.

No SGU will be transferred from the previous period. You will also loose all your previous project data. The status of your account will be identical to the new account after the new subscription period purchase.

Solargis units (SGU)

The amount of SGU you receive depends on your purchased price plan. You will need them to activate your projects, run simulations, or purchase add-ons. These services are priced differently based on the evaluation type selected upon project activation.

The following table provides general information about the cost of services in SGU. The price of SGU depends on the chosen Price plan.

Solargis Evaluate stages	Service	Unit	Value
Early evaluation	Project activation (TMY P50 data) Simulation services (price per MW)	SGU SGU	200 20
Full evaluation	Project activation (Time series +TMY P50 data) Simulation services (price per MW)	SGU SGU	600 60

The simulation cost model

You always pay for the first simulation of the energy system with the highest installed capacity per project. Each starting MW of installed capacity counts, thus 4.1 MW project is considered as 5 MW in the MW price calculation. If you create a second, smaller energy system and simulate it, there will be no extra cost. When you simulate an energy system with a larger installed capacity compared to the largest in the project so far, you will pay the difference only. This applies according to the selected project evaluation level (Early or Full evaluation).

Price per MW discounts

The unit price per megawatt (MW) decreases as the size of the system increases. The following table provides an indicative price reduction in SGU, based on the power plant size in MW:

Installed capacity in MW	1	5	10	25	50	100	250	500
Early stage (SGU)	0	100	200	460	840	1,520	3,320	5,920
Full evaluation TMY/TS (SGU)	0/60	300	600	1,380	2,520	4,560	9,960	17,760

Example:

Activate a project with Early evaluation (200 SGU).
Create and simulate a 50 MW energy system (840 SGU).
Create and simulate a new 30 MW energy system (No cost; previously simulated 50 MW system was larger and paid for).
Upgrade to Full evaluation (400 SGU). 200 SGU was discounted since it was already paid in the Early evaluation). Time series and TMY Pxx can be chosen in PV simulation from now on.
Create and simulate a new 50 MW energy system (2,520 SGU, then we deduct the previous simulation price: 2,520 - 840 = 1680 SGU).
Create and simulate a new 100 MW energy system (4560 SGU. Pay the difference only: 4560 - 2520 = 2040 SGU).
Create and simulate a new 50 MW energy system (No cost; a previously simulated 100 MW system was larger and paid for).

You are always informed upfront about steps where SGU are deducted, and this information is logged in the Evaluate usage history. All expenses can be monitored by the company administrator(s).

The example illustrates you essentially pay for the highest MW simulation per project regardless of the number of energy systems, always discounting the previously paid simulation, and the price per MW is based on your currently activated evaluation.
