Proposed load survey

Record one agreed customer load before sizing or buying the system.

Electricity as a service

The offer.
In three parts.

We fund the system

Solar, storage and agreed backup integration.

We keep it running

Monitoring, maintenance and an agreed response.

The customer pays by use

Metered electricity, with clear supply and fuel terms.

Where we start

Start with private hospitals and hotels in Greater Banjul. Check current solar assets, bills and the legal buyer before proposing a system.

The question that decidesCan one measured daytime load support a tariff that covers service and capital?

Critical clinical loads, grid export and capacity increases need separate engineering and agreed authorisations.

Service scope + market calculation

The customer buys

Metered kWh × an agreed tariff. Define availability, response times, billing, escalation and the term in the contract.

We provide

Financed equipment, installation through qualified specialists, monitoring, maintenance, repairs and agreed capacity upgrades. Extra capacity still needs an agreed design and commercial amendment.

What stays separate

Existing grid and generator energy/fuel, critical clinical UPS and major roof works need explicit boundaries. Surplus earns no export revenue until technical and commercial approval exists.

Build the market from qualified sites.

Signed annual delivered kWh × agreed tariff = contracted sales. Count sites only after decision authority, payment capacity, technical fit and current supply are documented. No 300-roof forecast is treated as secured demand.

02 / First installed project · scope checked 16 Oct 2026

What we need to procure
and put in place.

Solar modules

Example: 40 × 500 Wp = 20 kWp

Generate electricity for the agreed daytime load.

Scope + what to specify

Count illustration: 40 × 500 Wp = 20 kWp. No module model or supplier is selected. Confirm shading, usable roof, layout, yield, module certificates, hot-weather output and local warranty support. Actual string design and module count belong in the installer’s quotation.

Victron · ESS component guide NLR · photovoltaic standard work specification

Roof + mounting

One assessed mounting system

Keep the array secure and the roof watertight.

Scope + what to specify

Roof-condition/structural assessment, suitable rails and fixings, corrosion protection, roof seals, access and installation-at-height arrangements. Design for the actual roof and local exposure. Major roof repairs are outside the existing allowance.

NLR · photovoltaic standard work specification

Battery + BMS

Example: 8 × 5.12 kWh = 40.96 kWh

Store energy for agreed evening and backup needs.

Scope + what to specify

Illustrative LiFePO4 format: 8 × 5.12 kWh = 40.96 kWh nominal. No battery model or supplier is selected. Include a compatible battery-management system, cabinet/rack, battery disconnects/protection and temperature/environment provisions. Usable AC energy is lower and depends on operating reserve, losses and ageing. Choose capacity from required duty; storage can be reduced if the measured service does not need it.

Victron · Lithium NG battery datasheet Victron · ESS system design

Inverter + solar charging

One compatible engineered package

Turn solar and stored energy into usable building power.

Scope + what to specify

Select suitable inverter/charger equipment and the solar conversion path: integrated MPPT, separate MPPT chargers or an AC-coupled PV inverter, as designed. Avoid double-counting integrated functions. Phase count, continuous/peak kW or kVA and charge limits follow measured loads and the battery; 20 kWp of panels does not specify inverter output.

Victron · ESS component guide Victron · ESS system design

Cables + electrical protection

A fully specified AC / DC package

Connect and protect the complete installation.

Scope + what to specify

Include rated cables/connectors, containment, distribution boards, isolators, fuses/breakers, designed surge protection, earthing/bonding and any required lightning/fire provisions. The designer specifies ratings and quantities from routes, fault conditions, equipment and applicable rules. No generic component basket substitutes for the protection design.

Victron · Wiring Unlimited NLR · photovoltaic standard work specification

Metering + kWh billing

Customer meter + source measurement

Bill the electricity covered by the agreed service.

Scope + what to specify

Define the customer delivery boundary and an accepted billing meter, calibration/verification and readings. Measure grid and generator contributions where needed to allocate costs; a controller’s monitoring meter is not automatically a lawful revenue meter. Agree tariff, source-energy/fuel treatment and invoice checks.

Victron · ESS component guide PURA · electricity sector

Smart controller + connection

Controller · router / SIM · monitoring

Coordinate energy, record faults and arrange response.

Scope + what to specify

A compatible EMS/controller, required communication cables and a site-appropriate internet/data plan. Configure monitoring, local records when offline, alerts, permissions and backups. Start with standard tools and a simple invoice/maintenance ledger; a custom platform is not required for site one.

Victron · Cerbo GX monitoring

Grid interface + surplus control

Existing connection · approved design

Use the grid safely and control spare energy.

Scope + what to specify

Assess the existing connection, protection, metering and transfer/maintenance-bypass arrangement. Obtain the applicable NAWEC/PURA requirements, including anti-islanding and permitted operating mode. Surplus can serve suitable on-site demand or charge storage; when neither is possible, curtail. Export only under an approved technical and commercial arrangement.

Victron · ESS system design PURA · electricity sector

Existing generator + interface

Reuse only if suitable · no new purchase assumed

Cover agreed loads when solar and storage are insufficient.

Scope + what to specify

Survey the actual generator, controls, service condition, phase/rating and fuel responsibility. Specify compatible transfer/interlocking, input limits, start/stop integration if supported and maintenance bypass with the qualified team. A dual-input inverter is one possible architecture, not a selected model. The reference budget excludes a new generator and its fuel.

Victron · Quattro inverter/charger Victron · ESS commissioning

Installation + ongoing service

Qualified team · handover · spares

Deliver a working service and keep it operating.

Scope + what to specify

Include engineering, installation/lifting, independent checks as needed, commissioning, as-built drawings, test records, operator training, warranties and initial spares. Agree cleaning/inspection, fault response, local technician access and replacement reserve. Acceptance must test actual grid, storage, generator, metering and protection modes.

Victron · ESS commissioning NREL · PV and storage O&M best practices, third edition

For a hospital: start with agreed routine loads.

The hospital’s engineering team must define clinical boundaries. Theatre, ICU, medical UPS and critical redundancy are not covered by the generic 20 kWp / 40 kWh example. Neither a battery size nor a manufacturer’s transfer-time claim proves clinical continuity.

The project also needs people, rights and a commercial agreement

Three contributions.
One complete project.

Lamin

Secure the site and local operation.

Customer access, roof/site rights, local installer offers, deliveries, trained site contact and a realistic response arrangement.

Joachim

Own the complete technical brief.

Coordinate the qualified designer, structural/electrical checks, compatible bill of materials, comparable quotes and witnessed acceptance.

Dominik

Make the service fundable and billable.

Customer and our contracting entity, asset ownership, kWh agreement, approval route with advisers, funding, insurance and meter-to-invoice collection.

Bring in a qualified electrical designer/installer, a roof/structural specialist as required, a metering/generator specialist and local legal/insurance advisers. The founders coordinate the work; these specialist approvals are not replaced by founder experience.

The brief for comparable complete-system quotes

Design inputs: load file, peaks/phases, selected circuits, outage and fuel records, roof survey, backup target and existing assets.
Complete equipment: exact models, quantities, compatibility, protection, mounting, cable lengths, meters, controls, environmental limits and all integration work.
Delivered scope: freight, battery transport documentation, clearance/tax treatment, installation, approvals, commissioning, training, warranty and support.
Acceptance + cash: contracting/asset-owning entity, legal importer, agreed test protocol, exclusions, dates, staged payments, response times, insurance and funding through first collections.

What we keep from the supplied concept

The supplied Shade & Power concept contributes customer screening, financed ownership, local maintenance and eventual portfolio financing. Its fixed monthly plan, licensing workaround, assumed savings and 50 kWp return do not transfer to today’s metered, storage-inclusive model.

Quality + growth

Prove the essentials.
Then repeat.

Technical, quality and expansion requirements

01Choose the right configuration

Compare a daytime PV design using existing backup with a larger storage design. Do not size a battery from the building’s status or headline panel rating. Record peaks, phase balance, protected circuits, seasonal occupancy and evening load. A 14-day survey must be checked against seasonal bills.

02Keep the customer safe and the contract credible

Use a qualified electrical design, commissioning and insurance process. For hospitals, clinical engineers define critical-load continuity; a payment dispute must not trigger an improvised remote cut-off of clinical circuits. Local counsel must confirm lawful security, recovery and service terms.

03A repeatable commercial system

The digital record connects meter readings, invoices, collected payment, faults, maintenance and replacement reserves. Lamin coordinates local access and response; Joachim owns technical delivery with specialists; Dominik owns customer economics, billing and funding. These are proposed responsibilities.

Four conditions for moving forward · our decision criteria

Demand

One legal buyer, a defined load and written survey access.

What this test can establish

A measured load profile, a comparable design/quotation brief and a customer-reviewed kWh offer. This proves the basis for a proposal; it does not demonstrate uninterrupted power or an installed system.

Outside this budget / conditions

A PV installation, battery, new generator, clinical UPS, structural works, full electrical protection study, financing and grid-export approval. Rental availability and deposit must be agreed locally; an overseas shipment needs a revised quote before spending.

Planning allowances, not local quotes. Includes a 20% reserve; excludes founder pay and travel. No sales receipts are deducted.

Budget basis, exclusions + next-stage funding

All local prices, specialist day rates and the 20% reserve are proposed allowances until written offers replace them. Relevant overseas references appear in Sources; they are not Gambian landed quotes. Provisional tax/permission amounts are not legal rates. Founders’ time is unpaid in this test; founders’ pay and travel are excluded. Add them before approval if needed. There is no supplier commitment or booking yet. No paid goods are released without the applicable qualified checks.

The later deployment case below has a different scale and scope. Do not add both budgets mechanically: reconcile test spending and reusable assets already included in launch lines before funding the next stage.

Read the test correctly · calculated from the stated assumptions

The first test buys a decision, not a power system.

$2,254 funds a 14-day load study and proposal. It buys no solar installation and assumes no electricity sales.

Calculation + what the test can prove

The $2,254 test buys access, specialist measurement and a proposal. No electricity-sales receipts are assumed. The later storage-inclusive case needs about $0.453/kWh for its stated capital target, versus the $0.28 planning tariff. Compare an engineered smaller-storage option and the customer’s avoidable grid/diesel costs before funding equipment.

What the later investment model includes

20 kWp solar + roughly 40 kWh nominal storage. Existing customer generator integrated; no new generator purchase or clinical UPS included. This is a sizing hypothesis for an agreed load, not a whole-hospital supply design.

Outside the scope: Land purchase, major roof repairs, a new generator, fuel stock, clinical UPS, dedicated clinical redundancy, founders’ travel/pay and a second site. Add them if required; do not hide them inside the contingency.

Freight and provisional non-recoverable tax/clearance costs are inside the stated allowances where listed. Actual duty, VAT treatment, permits and charges still need a broker/accountant assessment. No tax exemption is assumed. Recoverable VAT, if any, can create an additional timing gap.

How to interpret and stress-test the result

What the result means.

The planning case can be cash-positive yet miss the ten-year capital target. The operating break-even tariff covers running costs and the reserve only; it does not recover the installation. Grid and generator energy must have separate meters and agreed customer-paid costs, or be added to the tariff model. No grid-export income is included.

Stress the case

First test: lower the sold share, increase battery replacement costs, and compare a smaller-storage design. A tariff premium requires a measured customer benefit and acceptable service terms.

Watch the cash timing

Bill monthly from the verified meter. Size liquidity for invoice delays and scheduled service. Stress a 15% GMD depreciation against USD equipment costs; a USD-indexed tariff is a negotiation and affordability issue, not an assumed right.
