Solar energy
COREVIA International assesses solar solutions from actual uses, site characteristics, energy priorities and the confirmed scope of work.
An approach based on actual use
A solar solution begins with understanding the appliances, operating periods, priorities and planned changes.
The site must then be reviewed: location, access, space, orientation, shading, support, existing source and installation constraints.
Sizing connects this information to an appropriate production, storage, conversion, protection and monitoring architecture.
The solution, equipment, work, schedule and performance are confirmed only after assessment and approval of the scope.
Needs that may be assessed
Each request is assessed according to its context, equipment, site and intended result.
Assess domestic uses, priority appliances and the desired level of autonomy.
The solution may cover selected uses or a broader scope depending on the assessment.
Assess offices, shops, workshops, tools and operating periods.
Review the need, access, environment, storage and operating constraints.
Identify critical loads, required operating time and complementary sources.
Connect the hydraulic need with the site, flow rate, head and pumping periods.
No pump, power rating, head or capacity can be confirmed without sufficient data.
Define the areas, uses, operating periods, location and maintenance constraints.
Prepare an assessment, maintenance operation, correction or upgrade.
No final diagnosis can be made from a photograph or partial description.
Check compatibility, available capacity, new uses and required modifications.
Verified projects
Possible services
Services are selected and specified in the proposal; they are not all automatically included.
Structure uses, priorities, constraints and missing information.
Review access, surfaces, supports, shading, equipment and visible constraints.
Prepare an estimate from the available data and clearly stated assumptions.
The level of accuracy depends on the quality of data, measurements and assessment scope.
Define production, storage, conversion, protection, complementary source and monitoring functions.
Arrange procurement when supply is explicitly included.
Carry out planned work after confirming responsibilities and site conditions.
Perform the planned checks and tests before handover.
Plan follow-up only when included in an agreement or proposal.
Possible architectures
Architecture selection depends on the actual need, site, existing sources and operating conditions.
For a site without grid supply or an independent use, the assessment reviews appliances, daily energy, simultaneous power, autonomy, storage, charging and maintenance.
Combine solar energy with another source when appropriate.
Compatibility, source priorities and switching arrangements must be assessed.
Maintain selected uses during an interruption according to the assessed scenario.
Supply a pumping need defined from hydraulic data and site conditions.
Assess independent or integrated lighting according to areas, operating periods and use.
Assess an appliance, machine or targeted use with its operating characteristics.
Upgrade an installation after reviewing the existing system, new needs and compatibility.
General architecture
Final selection depends on the assessment; this overview explains only the general role of the main assemblies.
Produce electricity from available solar radiation. The assessment reviews location, space, orientation, shading and electrical compatibility.
Holds modules on the selected support. The site, access, mounting, exposure and maintenance must be reviewed.

Possible assessment or assignment outputs
Not all deliverables are systematically included. Their content, level of detail and contractual value depend on the accepted scope.
A conceptual diagram should not be presented as an execution drawing when that level of detail is not included.
Understanding estimates
Sizing is based on consumption data, usage assumptions, site information and technical parameters. The result remains an estimate subject to actual conditions.
Solar production varies with solar resource, weather, temperature, orientation, inclination, shading, cleanliness, losses and equipment condition.
Autonomy depends on usable storage capacity, actual consumption, priority loads, battery condition, charging conditions and possible complementary sources.
A change in appliances, operating periods or priorities may make the initial sizing unsuitable and require a new assessment.
Varies with location, period and site conditions.
Influence production and charging scenarios.
Are reviewed according to available surfaces and constraints.
May change with time, season and surroundings.
Affects equipment behaviour according to its characteristics.
Depend on architecture, equipment and installation.

How we may deliver the service
Assessment, sizing, installation and maintenance may require accurate technical information, a site visit and physical intervention.
No installation should be confirmed before a feasibility assessment.
The quality of received information does not replace a visit when site conditions must be checked.

Assessment and development
An existing installation may have missing documentation, equipment from different generations, changed uses, intermittent faults or insufficient capacity.
No final conclusion should be published from a simple remote description when measurements or inspections are required.
Specific application
Pump and supply selection does not depend only on electrical power. The assessment must consider water, head, flow rate, storage and use.
No pump model, flow rate, power rating or number of panels should be confirmed without sufficient data. This section performs no hydraulic calculation.
Priority loads
A backup solution should not be sized from all appliances when only some are genuinely critical.
Total continuity should not be promised without assessing loads, sources, storage and actual conditions.
Essential conditions
Visitors should not be invited to reproduce an installation, open an inverter, handle batteries, work on an electrical panel or work at height from the information on this page.
This information replaces neither a site assessment nor work by competent personnel.
This page presents needs and services that may be assessed by COREVIA International. It does not constitute a technical proposal, sizing result, quotation, production guarantee or installation confirmation.
Frequently asked questions
Useful information includes the location, appliances, quantities, power ratings, usage periods, priority loads, desired autonomy, existing source, bills, photographs and available space.
The bill may be useful, but it does not always describe the appliances, operating periods, priority loads, simultaneous power or future needs. Additional information is generally required.
The number depends on the energy need, characteristics of the assessed modules, site, solar resource, losses, space, storage and objectives. It should not be confirmed before sizing.
Autonomy depends on usable storage capacity, actual consumption, priority loads, charging, weather and equipment condition. It should be assessed from a usage scenario.
Solar production may continue under some conditions, but it is generally different from production under better sunlight. Storage, uses and complementary sources should be assessed accordingly.
This depends on power ratings, operating periods, simultaneous use, starting requirements, budget, space and desired autonomy. It may be appropriate to distinguish priority appliances from secondary uses.
Supply may be included when specified in the proposal. Brands, models, quantities, characteristics, availability and warranties should be confirmed.
Installation may be included after site assessment, scope approval and confirmation of equipment, access, responsibilities and safety conditions.
A solar pumping need may be assessed. Selection depends on the water source, depth or head, flow rate, distances, storage, intended use and site conditions.
Yes, subject to feasibility. Information, documents, photographs and symptoms may help prepare the intervention, but a visit and checks may be required.
An installation should be monitored according to its equipment and environment. Maintenance provided by COREVIA is included only when specified in an accepted agreement or proposal.
The cost depends on the needs, architecture, equipment, storage, site, work, protection, transport, installation and included services. An estimate is prepared after assessment.
The schedule depends on the assessment, approval, equipment availability, location, preparation work, installation and checks. It should be confirmed in the proposal.
Each request is assessed according to the service, location, accessibility, resources and delivery conditions. COREVIA’s presence in Mbankomo does not constitute automatic coverage of another area.
Prepare the location, appliance list, available power ratings, operating periods, priority loads, desired autonomy, photographs and existing documents, then submit a quotation request.
