We develop solar energy project plans with PV*Sol, PVsyst, and AutoCAD systems which includes yield forecasts, module layout, solar substructure plans, and technical documents.
A transparent and seamless step-by-step journey from our first hello to the final results.
We get together to understand your needs and project goals.
We start with a small assignment to ensure we're a perfect match.
We agree on the terms and step into an amazing partnership.
You are invited to our custom portal for transparent project tracking.
We officially launch the project and jump straight into action.
Sit back, relax, and enjoy the flawless results.
The performance of a photovoltaic system depends not only on the quality of the panels but also on the expertise in engineering and system design. At Lion Solar Solutions, we provide site-specific and data-driven solutions to ensure maximum returns on investment across both Turkey and Europe. Our professional engineering support ensures the optimization of system performance and cost-effectiveness at every stage of the project. Whether in Turkey or across Europe, each photovoltaic project is executed with technical precision, transparency, and verifiable results, guaranteeing superior efficiency and affordability.
Utility-scale site optimization and bankable production simulations powered by PVX and PVsyst.
Engineering plan for shading, orientation, tilt, and structure optimized systems.
System yield calculation and loss analysis for standard-compliant systems
Technical project detailing with professional dimensioning and schematics.
Every roof needs more than just a layout it needs a structurally sound mounting plan that fits the building type, meets local load standards, and actually works in the field.

Our prices have been studied for a long time and now online to everyone, we are trying to be transparent on this matter, prices per project can be around 25€-20€, respectfully to the package size.
We are eager to sign any NDA you would provide us because we care about your information’s security. If you don’t have any NDA template, we can send you an agreement too.
Yes, if you provide us your company branding such as your logo, contact information etc, we as our standard process provide you plans with your branding.
Typcial turnaround time is 24 hours, We are giving a commitment as we will provide your study in 48 hours, but still when you are at customer visit and/or you need something very urgent we are pushing ourselves and trying to finish the work in the same day.
Yes, for our first encounter, we are providing you one free test project so that you won’t take any financial risk while making any decision.
Yes, if you can send us a pile of pictures taken from a certain height, we can provide you a 3d modeled PVSOL planning too, with using our beloved tool Render-a!
We provide comprehensive solar energy solutions worldwide. Our services include production planning with PVSOL and PVsyst, DC and AC electrical design, as well as construction and infrastructure planning using leading industry-standard systems.
Our headquarters are located in Tartu maakond, Estonia. In addition, we provide services through our branch office in Turkey.
All of our packages are credit based. We do not charge monthly fees; instead, your package remains valid until your credits are fully used. Once your credits are exhausted, you may choose whether to renew your package.
Yes, we offer comprehensive electrical engineering design services for solar energy projects. All designs are developed according to the latest standards and include the required documentation for official approval procedures.
We are a team of 12 specialists with proven expertise in PV yield simulations, component selection, and electrical and structural project design. All official approval and permitting processes are managed seamlessly within our organization.

A bankable report must meet strict lender standards to minimize investment risk. It goes beyond basic simulation by including site-specific meteorological data analysis, detailed shading losses (near and horizon), a full breakdown of technical losses (soiling, degradation, cabling), and a rigorous uncertainty analysis.
Effective yield is the net energy delivered to the grid after all system losses are subtracted from the theoretical potential. Our calculation factors in specific variables such as temperature coefficients, inverter efficiency, IAM (Incidence Angle Modifiers), and detailed shading profiles to ensure the most realistic production forecast.
The 120% rule limits the amount of solar power that can be backfed into an electrical panel. It states that the sum of the main breaker rating and the PV breaker rating cannot exceed 120% of the busbar rating. We strictly adhere to this rule in our designs to avoid costly main panel upgrades for your projects.
Beyond standard system losses, accurate reporting requires detailed analysis of site-specific factors. We incorporate specific loss values for LID (Light Induced Degradation), mismatch, DC/AC cabling resistance, and realistic availability factors to ensure the production forecast is both safe and reliable for investors.
You can cancel your subscription at any time directly through your billing dashboard within the Client Portal. It is entirely self-service, and no prior notice period or manual written request is required.
No, your subscription will remain active until the end of your current paid billing period. You will retain full access to the services during this time.
No. All sales are final, and subscription fees are strictly non-refundable. Because fees are based on allocated capacity and system access rather than actual usage, no pro-rated refunds or credits will be issued for any unused time or unused project volume in your billing cycle.
No, payments for bulk or custom credit packages are non-refundable. Credits represent a non-monetary right to utilize design services and have no cash value.
Yes. All purchased credits must be used within twelve (12) months from the date of purchase. Any credits left unused after this 12-month period will automatically expire and become void.
